David's flat was perfect for my stay with a friend. Communication before our stay was very quick and helpful, even organising a lift to the flat in the night on arrival, at a very reasonable price. Despite arriving well into the evening, David was there to greet us and provide us with tips and show us points of interest on the map in the room. (I think David has recommended this, but again, 'honest guide' on YouTube was very useful beforehand, to tell where to go and what to avoid). The flat was simple but pleasant and was very quiet and secure, with all the amenities you would need for a short stay. The location is very central and close to the metro and tram, and is well lit at night. If you're looking for an affordable but comfortable place to stay in Prague then this is the place.
