My girlfriend and I spent a night at Alexander’s place while in Amsterdam. It’s compact, but has all the basics needed for a comfortable stay-and it is in a perfect location! The place was clean, the bed was very comfortable and we had a relaxing nights sleep. The apartment is a walk up a few flights of narrow stairs, which was fine for us but worth considering if you are less mobile or have a lot of heavy bags.
Alexander was a good host - the rules and times are quite rigid but clearly communicated up front. We only saw him briefly but he was friendly and he was responsive to our messages.
All in all, I would not hesitate to recommend this Airbnb if you’re looking for a simple, central and comfortable base to explore Amsterdam and all it has to offer!
