Great location, in the center of Vienna, close to tram, bus, and underground station. There is a very nice cafe just downstairs, and many others cafes and restaurants in a short walking distance. The main museums are also a short walking distance. The apartment is big with one big living room with a place for three beds, and one additional room with one bed.
The kitchen is very basic, and located inside a closet.
If you want to cook anything beyond a basic breakfast this apartment is not ideal, however for us this was not a problem because we ate out, and even had our breakfast at the cafe downstairs.
The apartment is clean, and rather quite despite being located in a main street. Check in was great and the host waited in the apartment as we arrived.
