Siep was very flexible about our arrival time and welcomed us quite late at night with open arms.
The apartment was perfect - clean and tidy, spacious, beautifully lit and in general looks as good as the pictures do.
The balcony is also a great place to spend some relaxation time.
The location is great - a drop outside the noisy part of the city but within 5 minutes walk from the center and other attractions (having been to Amsterdam a number of times, I feel that the area is the best part of Amsterdam to stay in).
Siep was very accommodating, offered to help with anything and was a very good host.
I would be more than glad to go stay there again!
