As a group of friends we found Nina's apartment a lovely, spacious, convenient place to stay. The apartment was clean and tidy with all the facilities required for a weekend break.
The apartment is situated in a quiet neighbourhood with plenty of good lively bars and restaurants within easy reach. The location is a little way out from the centre but it is easily reached by several nearby tram lines.
I would recommend Nina's apartment as a great place to stay whilst in Amsterdam.
