David was an exceptional host who greeted is personal upon arrival. He took the time to explain the apartment and the nearby area to us, which was very nice and useful since the three of us we're only in Prague for two short days over the weekend.
The apartment was accurately described and actually had three beds in separate rooms, though one bed shares the room with the only TV in the apt, but you shouldn't come to Prague to watch TV. The bathroom is effectively one full bathroom split across to separate rooms, so one guest can shower or bathe without making the only toilet inaccessible. As a very nice bonus, David's cleaning service ran the very small amount of laundry we had left in the apartment while we were out, and the clothes were on the rack drying when we returned that evening.
The location is also amazing. You are only steps from the Kafka Memorial statue and can easily walk to the Old Town Square, the bridge over to Prague Castle and St. Vitus' Cathedral, the Jewish synagogue and cemetery as well as to pretty much any other point of interest you could imagine.
In sum, if you are two to three people visiting Prague, then I would must certainly recommend that you do yourself a favor and stay at David's flat.
