In short, I wouldn't recommend at all this apartment.
Too many stairs. looks a little broken. The water in the shower doesn't empty so a lot of water stays on the floor and I had to clean it up every time. The owner asked to be quiet since everything can be heard because it's an old building. This wasn't mentioned when I ordered the apartment. Also, he put something that can hear our sounds, I don't know if he recorded us or no. But it really strange to me that somebody does all this and then makes a lot of sound in the morning when fixing \ building the upper floor without telling \ asking us. He asked surprisingly to enter the workman to fix something in the apartment. He didn't arrive for check-in or check out and claimed we left spot them unremovable.
The vacation around Amsterdam was really great, but the apartment ruined it all.
Ric claimed that I left the unremovable spot and asked to pay for a whole new shelf (about 96$). I sent him a text message before I left, but he didn't arrive.
If I were you, I would choose another apartment or record \ picture every little spot before you enter the apartment.
However, there are some good parts. When I met Ric in the corridor he sounded nice person. The apartment close to the center, but you still have to take bus to get many places (unless you prefer to around 15 - 20 minutes). The public transportation is pretty good and cheap so it's ok.
