My friend and I stayed for 2 nights at a Rosa's apartment and I can't recommend it highly enough. The location is perfect. There are bars/restaurants/shops on your doorstep. The area feels very 'local' and not touristy.
The apartment itself is very quiet and peaceful. It's super clean and well equipped. The stairs are very steep (typical of Amsterdam) so travel light! It's a perfect size for a couple. The balcony is an added bonus too.
Rosa was the perfect host. She met us on arrival (despite our late flight) and greeted us with a bottle of wine! She left maps/recommendations and then left us to enjoy. We were able to have a later checkout which was amazing.
All in all my friend and I had a superb time in Amsterdam for 2 nights and that was a lot to do with our fab choice of an Airbnb. Thanks Rosa!
