The apartment is really good. It's big and really clean. It's obvious that the owner lives there by himself and cares about it a lot. The location is good too, there are supermarkets close to it, tram stop in 2 minutes and the neighborhood is very quiet and cosy. I didn't meet Luis in person, but online conversations with him were nice. He provides all information you need for comfortable stay. Thanks Luis, I had a good time in Amsterdam.
