David picked us up at the bus station and, as we rented it although the apartment was only free after 7/8PM (but we arrived at noon), he let us store our luggage in his car. He then brought it to the apartment and carried it up there for us, so everything was arranged for us when we arrived in the flat after our first afternoon in Prague.
He also arranged quite a stock of literature about Prague, as well as maps and so on, which proved really helpful to us.
The apartment itself was really great- very clean, with lots of devices and basic needs-stuff. We felt very comfortable there. Also, it has a central location and a really cool park nearby. Additionally, it was surprisingly quiet (at night & morning), although it was quite centrally located.
We really had everything we needed and if we would have had anything coming up, we could have always called him.
All in all, staying at Davids apartment was a real pleasure and we can recommend it to everyone! Thanks a lot, again :)
