I’ve stayed in Amsterdam for several weeks at a time on several occasions for work, and the Old South neighborhood is an ideal location to feel at home. Cafes, bars, Vondelpark, and beautiful streets and shops.
This room is in a prime location with access to everything and a fifteen minute tram ride into the city center. Museums are a ten minute walk.
In terms of the actual unit, it is more like a hotel room than an apartment, so whether that suits your needs depends on what you are looking for.
Access is provided using for digit codes, which is very convenient for check in. There are no keys to carry with you. However, there also is no kitchen or couch (only a narrow bench along the window), and the round table provided is too small to be usable other than to put your wallet and keys.
I mentioned this to Pieter, the host (who lives in the building on the floors above and was extremely helpful), and he may make some changes to make the unit more user friendly, but this was the set up when I stayed.
Ultimately, the unit is very stylish but could be made more practical for every day use. For a few nights, this would be a great place to stay if you are looking for an alternative to a hotel, but you are then giving up the amenities of a hotel without the benefits of an apartment.
