The apartment is very nice, big, confortable and light (last floor).
The Vinohradska area is pleasant, residential but with many shops, very good to go out (restaurants, clubs), not touristic but very close to the center.
Rob and Pavel are very nice hosts, reactive and helpful. I had a big problem after leaving and they really helped me to sort it out. Thank you very much ! I recommend you warmly and will definitely come back to you when I am in Prague again.
