The apartment is huge, indeed in the best location in Prague - short walking distance to all the attractions and with numerous restaurants and shops near by.
The building is very nice, with convenient entrance and elevator. The apartment itself is very equipped (washing machine, toys for kids, information about Prague, etc.).
Vera was very responsive every time we needed.
We do feel the apartment could use a small renovation and a better maintenance between guests, especially the old bathrooms/toilets and the wall to wall carpet, and it effected our overall experience. We are sure that if broken things will be fixed / replaced, the apartment will be great for future guests.
