The flat is excellent -- spacious, convenient, very clean and has all the amenities. The neighborhood doesn't feel the safest after dark, but is perfectly fine during the day. The building itself is very safe. One note to future guests: open the key code/security link BEFORE going to the store to pick up the key so that you know exactly which store you are supposed to go to. In our case, we made a mistake on internet search that sent us to an obsolete location.
The GuestReady support was very good -- we felt that we could get answers and help round-the-clock.
Overall, a very comfortable stay -- fully recommend!
