Frederique and her apartment are definitely worth a visit! Frederique was a lovely host, super flexible towards check-in time and provided us with tons of hints and tips for Amsterdam.
The apartment itself is well-equipped and super quiet, although it is well-located and really close to the next tram station. Frederique did a great job in furniture the apartment, so it is very comfy and beautiful. It also has a big terrace in the back - so in summer that is really an additional argument to book the apartment.
