This was the first time I book through this site, so here I will try my best.
Staying in Sebastiaan's room was nice, with its pros and cons. We were welcomed with a bottle of nice red wine by the (SENSITIVE CONTENTS HIDDEN) Nils and Michael, which were both really nice, friendly and helpful by providing us tips about the area, where we were located. They let us know how things at their home function, showed us the place and offered us fresh clean towels in a clean room. The room is cozy and clean with a bed that feels like you are laying on a cloud :).
The flat is fairly clean, you can tell the (SENSITIVE CONTENTS HIDDEN) work as a team to maintain it. It is located in a nice area near the Amstel, tram station at the corner of the street and a decent walking distance from the center of the city.
As we were warned by our tour guide on our first day in town, the walls in Amsterdam are very thin and you can hear pretty much everything and everyone. Besides the main point that my boyfriend and I, who were staying here, are like 70yo people and we don't go often out to party, as well as we enjoyed the city during the day for about 9hours walking around town, when we went back to the room we had a bit of trouble to fall asleep during the 3 nights. On the first night there was a gathering of friends in the kitchen, which is located next to the room, but it did not go for too long passed midnight. The second night, there was also some loud tv noises but we slept through it. The third and last night, there was again loud tv noises, I was too tired but my boyfriend did request to close the living room's door because we had to wake up on the following day at 5am to catch our flight back home, one of the (SENSITIVE CONTENTS HIDDEN) (which I forgot his name) was very kind to close the door and lower the volume to help us sleep. I most say that Sebastiaan did tell us it is a home with 5 (SENSITIVE CONTENTS HIDDEN) and it will not be fully quiet there, but we wanted to enjoy the day and were completely dead by 10-11pm.
Besides that, I enjoyed to meet some of the (SENSITIVE CONTENTS HIDDEN) and maybe next time that I visit the city again we can even grab a drink with them. If you are young, you like to meet new people and you like the nightlife more then you should stay here because it is very friendly, nice and super convenient.
