It was 3 couple going to Amsterdam for a long weekend and, after much research we decided to stay at Ivan's place.
The apartment is nice but it has to be noticed that this is not a 3 bedroom apartment as the 2 upstairs rooms are connected with no indipendent access which means low privacy.
It is also worth to notice that the place is about 20 minutes walk from the central station and not 10 as advertised. The house is clean and it would have been nice to have some decent towels instead of 6 (quite small ones) for shawering and an extra small one to dry your hands. The area the apartment is located in is nice and quite with some local restaurants and pubs nearby.
The check in was fine as Ivan was waiting there for us. I am not sure it was worth the €150 per night per couple we spent for it.
