This is more of a private sub-unit than just a bedroom, you're sequestered from the rest of the family home, so both you and David's family get total privacy. The location is in a residential neighborhood, about a 15-minute walk from the train station, and 20-30 minutes to the center by bus (one bus stop is very near, or the 'B' tram is a 10-min walk).
The only persons I would not recommend David's place to are very tall ones, especially if they are traveling with someone. I'm 6'1" and I kind of had to jiggle my way up to the headboard so my feet don't hit the other end. The bed is between two walls, so people much taller than me just simply can't fit.
Altogether, a very good experience!
