We had a wonderful stay at Evert's handsome, well-located flat. He could not have been more helpful and was easy to communicate with.
The unit is on the first floor (which in America would be called the second floor) and there is a very, very steep set of stairs to climb. I had back surgery a few years ago, so at first I was a bit taken aback, but we got used to the stairs and managed fine. If you have physical limitations, you should take this into account.
Evert has impeccable taste. The overall feel of the place is more eclectic chic rather than elegant, but it's a great suite. All the amenities--coffee, tea, mini-fridge, etc, are provided. The bed/linens are also top-notch.
