I had a lovely time during my stay with Martijn and his girlfriend Betina. They were super friendly and willing to help me or give me some nice advice about Amsterdam! The room is cozy and clean with a nice view on the garden and the bed is amazingly comfortable (loved the huge, soft pillow!). I also appreciated that I could use the kitchen to cook something for mysel.
The neighbourhood, Bos en Lommer, is an upcoming, but still not much touristic, area with lots of nice restaurants, bars and shops. The centrum is still easy to reach by bike or tram (within 10/15 mins).
I totally recommend this accommodation :)
