Martin is very nice and extremely kind. He was very flexible with the time of check in and check out.
The apartment was nice, like in the picture, less than 15 minutes by bike from the citycentre. Three things I'd outline:
- the flat is at the top floor: not a problem for me and my friends but I guess that for someone else could be
- the extra bed is the couch you see in the picture, but is comfortable like a normal bed
- the bathroom is a no-window-bathroom
I would surely suggest Martin's place for a few days trip to Amsterdam!
