I stayed three nights, it was a very last minute booking and nonetheless Xsjong reserved me a very warm welcome. As many other guests have already written, he is a really nice person, incredibly helpful. Everything was more than ok. Still, I would make some little remarks. The single room I was staying in is really next to the bathroom. If there are other guests staying in the apartment make sure that they are careful at night because you can get woken up easily. I must say that it might have been nice to have some tea bags and coffee for the morning, although I know that there is no breakfast included in the rental (there are no cafés really closed to the appartement). Then one very last thing is for people who are planning to have activities until late in the evening. The last bus leaves Buiksloterwerg (Amsterdam Noord) at around 23:45. If you have to get back later than that, you are then better to have a bike!
