This is an apartment in a good location, near the cafes and restaurants of Mala Strana. The management was friendly and super-responsive; check-in and check-out were very easy. Two sets of keys were provided, which facilitated our comings and goings.
But people considering booking this flat should realize that it is actually a subdivided large flat. (The building seems to have quite a few of these, as the original old apartments were quite large.) But in the subdivision process, the living spaces have been removed. So the flat as it is rented now is basically two bedrooms, with a shared bath/toilet and kitchenette. There is no living, dining, or sitting room. One of the bedrooms has a decent closet armoire; the other one has no space to hang clothes, only storage cubicles. Only one of the bedrooms has a TV set.
The kitchenette was small but functional. There were few amenities provided. (Ground coffee - yes. Sugar or creamer/milk – no.)
Note that the washing machine referred to in the description is in the building, but not in the apartment. (The management kindly provided a wash-and-dry service using that machine, for a very reasonable fee.)
