Our room is big ( 30m2) and cozy. It is not souless "perfect" room from the catalog, it is perfect in its imperfection room with ppl living in it, most of the time. Big mattress ( +1 if u need . It is located just in city center, 2-3 min. by foot from museum. You will have a lot of restaurants, shops and all 3 lines of metro nearby. We have a road near museum, so it is not perfectly quite, if you will open windows. But we are sleeping with close and it is totally ok;) So don't worry.
