We stayed at Davids place for two nights. He was really flexible with the check-in time, so we met early at the day. He was friendly and gave us some instructions for the place. Also there is a nice map of Prague, on which David showed us some good places in the city. :)
It was a nice stay at his place. You got everything you need and you are within a few minutes at lovely places in the old and new city. Definitely recommend to stay there.
