The Austria Trend Hotel Europa Wien has technically been open for over a century, although it was destroyed during World War II and subsequently rebuilt. Rooms have simple, streamlined modern decor, and pets are allowed. Wi-Fi is free but there's a fee for the breakfast buffet. The hotel is located right at Karntner Strasse, Vienna’s most popular shopping and pedestrian area, making it easily accessible to shops and restaurants, and while this location is suitable for tourists and business travelers, those in need of conference facilities may want to look elsewhere. 

In a 19th-century city palace, the Austria Trend Hotel Rathauspark Wien is a mid-range hotel with 117 rooms. It is centrally located five minutes away from a tube station and near shopping and historic attractions. All of the simple rooms have free Wi-Fi and flat-screen TVs, but they lack air-conditioning and some are a bit tight on space. This value pick could do with updating in some parts of the hotel, but generally it is clean and the staff is welcoming. There is a small business corner, lobby bar, and concierge services available, but there are fees for breakfast and parking. 

The Altwienerhof is a small, mid-range hotel near lots of public transportation options and within a short walk of Mariahilfer Strasse, known for its great shopping. The hotel is housed in a building dating back to 1892, and its age shows: both in the elegant old furnishings and the creaky floors. The rooms fit into the character of the hotel, but despite the attempt at period furnishing, they're missing finishing touches as well as most modern amenities. Free breakfast and Wi-Fi help keep costs low.

An upscale design hotel located in the city center, The Guesthouse Vienna opened in late 2013 with a warm modern look that contrasts the gilded interiors of the city's more established five-pearl palaces. Luxury here comes not from marble and priceless antiques (there is some of the former, none of the latter), but from a cafe that churns out incredible baked goods and roasts its own coffee. There's no spa or pool, but every room has a wine fridge stocked with multiple bottles from the region, and it's free for guests to drink. Business travelers might miss work desks, and glass bathroom doors mean that rooms aren't great for sharing with friends -- or kids.

The five-pearl Palais Hansen Kempinski occupies a building that was originally designed for the 1873 World Exhibition in Vienna, and while some of its palatial interiors remain, it has since been given a complete modern renovation that combines glamour with high-tech amenities. Large rooms decked out in rich natural materials all have Nespresso machines and iPad controls for everything from adjusting the thermostat to booking a treatment in the hotel's well-designed spa. One of its two restaurants earned a Michelin star within a year of opening, and the other serves an incredible breakfast spread. All this luxury comes at a high price, though, and that great breakfast is not included.

The mid-range Hotel Das Tigra is notable for its central location and serious breakfast spread featuring Viennese Bundt cakes. Rooms are comfortable and modern -- some have hardwood floors and suites include private saunas. The rates are reasonable compared to other similar hotels in the heart of the city, and free breakfast and Wi-Fi keep rates low. The ambience is historic (Mozart lived in the building in 1773) and there are modern meeting rooms and a small bar, but the hotel lacks a full restaurant and there's no fitness center. 

A grand 19th-century institution, Hotel Bristol Vienna is an elegant luxury property right across from the Vienna State Opera. It's a long-time favorite of opera fans jet setters. Filled with marble and brass, antique crystal chandeliers and stained glass, it's seen over a century of esteemed guests. Many of the rooms underwent a facelift in 2013, although some rooms still have older, classical decor. Both traditional and remodeled rooms combine an elegant setting with modern amenities such as rainfall showers, but they lack coffeemakers. Amenities include a fine-dining restaurant and 24-hour fitness center, though Wi-Fi is disappointingly an extra fee. 

Hungarian-based Mellow Mood Group got its start in youth hostels, but its first foray into Austria is the three-and-a-half pearl La Prima Fashion Hotel. The hotel is a bit outside the city center, though fashionably close to the dining and cafes at the popular outdoor Naschmarkt. There isn't much going on at the hotel itself apart from a decent breakfast, which isn't included in standard rates. Only its Suite and a few Superior Rooms could be considered truly upscale, but savvy travelers can find a much better value here than at similar nearby hotels.

Hotel Zeitgeist is an upper-middle-range, very modern design hotel with a degree of edginess in Vienna's up-and-coming Sonnwend quarter. Although a good couple miles from the city center, the hotel is just five minutes on foot from the main train station, which offers connections throughout the city. Rooms are suitably contemporary but also comfortable -- adjustable mattresses make for an unexpected bonus. A rooftop sauna and hip cafe-bar add a couple touches that make this hotel a decent choice -- and with rates that are more than reasonable. 

The boutique, upper-mid-range, Hotel Konig Von Ungarn has been in operation since 1746, making it one of the oldest hotels in Vienna. Its classical restaurant sits below apartments that Mozart once lived in, and the central courtyard's glass ceiling makes for a great place to lounge in the heart of the city. Apart from the two-story suites though, the rooms tend not to be as interesting as the rest of the hotel and there's an odd mix of styles, with a quaint old-fashioned decor in one section of rooms and a bold modern design in another. Rooms facing the street can be noisy, so light sleepers should request interior rooms. Free breakfast and Wi-Fi helps to keep costs down.
