We had a really nice time in Amsterdam and at Jan's place at last weekend. Jan was really friendly with us and so open minded. We had a great time all together (have dinner, drink beer, smoke some weed and play pinball machine). Was funny to be a translator guy because my friends aren't good with english and I'm glad to know that we were the first portuguese guys to rent the Jan's apartment.
The apartment was comfortable and clean. Close to the public transports to go to central station (4 stops by bus) and in a very quiet street. I'm sure We are going there again and if will be available, I will rent it again! Thanks for all
