David's apartment is simply amazing! Sunlight at all hours, in a lively neighbourhood just a quick stroll from the city centre. We stayed there for over fifteen days and enjoyed every minute of it. We did not know that due to security concerns only one set of keys is provided per group of guests; this is perfectly understandable, of course! Just keep in mind that if your group is not going to go everywhere together it may require some coordination. This is just a minor issue, of course, and have we mentioned the apartment is just amazing? :)
