Nick's place is perfect: great location (just behind Rembrandt museum, in a block full of things to do & see), nice and quiet apartment: we really appreciated the furniture and we slept greatly. The apartment is big enough to allow the two bedrooms to be booked by strangers without interfering with each other, plus there are keys to lock the bedroom doors.
Nick has been a great host, too: he left clear instructions to self check-in and has been really fast in answering any doubts or needs arosen during our stay.
Definitely recommended!
