I visited Amsterdam for a short trip and it was a really nice stay in Marielles apartment.
The flat got a good location relatively near to the inner city and is well conected by the public tranpsort. So you can reach the most things easily by foot or by the public transport. Restaurants and supermarkets were also nearby. It was easy to find the way from the airport to the apartment due to Marielles precise instructions. The check in was also very smooth and easy due to the Keybox.
Everything seemed to be good organized.
The apartment was clean and got a cozy ambience at the last floor under the roof. The apartment is good equipped just the stairs to the last floor are really steep. It may be a problem, if you are not good by foot. There was also a guide book in the room with recommendations by Marielle which were very helpful.
The check out was also nice and easy. The communication with her was also good. She checked from time to time if everything is ok and Marielle itself is also a friendly Person. :)
I would recommend this Airbnb and would definitely book again. :)
