Small flat (first floor) in the very centre of Praga, 3 minutes on foot from the Old Town square. There were the 4 of us: 2 adults, 2 kids (6 and 10 yo).
The flat is located inside a courtyard (closed after 6pm), so it is really confortable, secure and not noisy. It's tiny and clean (we didn't use any kitchen items: there are plenty of places to go eating very close to the flat)
Vadim's person was there right on time (that we had stated) awaiting for us.
It has been defintely a very good experience.
Tnx Vadim
