Xsjong was a great host, and his place is very nice. He provided a lot of tips about the city, and you can tell he loves Amsterdam and wants people to love it too :P.
The location is in the outskirts of Amsterdam North; it's a very quiet and tranquil place, perfect for a relaxing time and good sleep. The city center is about 20 minutes from his place, which might be good or bad, depending on what you're looking for.
The apartment is pretty, clean and organized. The bathroom is gorgeous, and the rooms are comfortable and well equipped.
I had no problems whatsoever during my stay, but Xsjong would occasionally check up on me regardless, just to make sure everything was OK. He was very attentive to detail and wanted to make sure I enjoyed my stay.
