The Mansion is a clean, roomy apartment with two bedrooms and a sofa bed in the lounge, so it comfortably slept our group of 3. The layout is a bit strange, in that the bathroom with shower/bath is an ensuite of the large bedroom, meaning all guests must pass through this to use it. The check-in was smooth - Susan was great and met us at the apartment, but we did have to wait outside for 10m. Communication with Dries and Susan was excellent - they were always available and when our flight was cancelled they were flexible to help us check-in the next day. The stairs are incredibly steep, and the apartment is on the 3rd floor - going up/down that with a heavy suitcase is quite dangerous, so tread carefully. The location is fantastic, a short walk from the main city squares and the wonderful Vondelpark. I felt the price was quite high for what it was, but we booked on short notice and the location is amazing, so it's understandable. Overall, very happy with our stay.
