Overall, I had a fine experience that could have been better in just a couple key areas. The hosts were nice and accommodating (although I only ever met Gina's husband), and the room was absolutely fine. They provided plenty of blankets + a small towel for me. The neighborhood was cute, quiet, and residential, with tram/bus stops nearby and Westerpark, a nice park with ponds, willows, and really funny birds.
However, I have serious asthma, and the hosts smoked in the living room/kitchen. Even though the door was kept closed, the whole place had a strong cigarette smell, including my room. When I asked them not to smoke inside, they were very understanding and nice (but of course, the smell was still everywhere). I should have searched the reviews for "smoke" and have learned my lesson for the future. Also, as a warning for light/early sleepers: The TV in the living room was very loud (explosions!) until around midnight, despite closed doors. But I'm sure they would turn the volume down if asked - I stayed up a bit late too, so I didn't bother asking. Finally, the location not as centrally located as advertised, a bit far from all the main attractions: it took me a half hour or more to walk anywhere. It's a pleasant walk though :P
