Everything was really great! Nice things start to happen even before you get the keys: free parking (in both meanings of "free") is really fantastic thing in Prague. Perfectly clean apartment (everywhere, from beds to kitchen), warm floors (we were here in winter), stable and fast wi-fi, comfortable and well-planned interiors.
Food store is not far away from the residence, so you can get everything you need almost "from wheels".
Useful recommendations were provided for things like exchanging money, getting a taxi, nice places to visit and so on.
In short: it is a great choice to stay in Prague!
