Our family of 4 had an incredible stay in the Museum House! The location could not have been better - we walked daily to incredible museums and parks and restaurants, and we were an easy train ride to other area attractions and restaurants. We also very much enjoyed our time while in the house. It was comfortable and spacious enough to invite friends over, the kitchen was perfectly equipped (fun coffee mugs included), and there was daily access to the owner's pool and patio as well. The best part about the stay, however, was the host. Hans was so kind and helpful, it was almost as if we were visiting friends. We arrived to a welcome basket, and he was responsive to texts throughout our stay and sent several updates of local goings-on.
Although we were traveling with 2 young children, I would probably not suggest this home to all families. There is a lot of very valuable and very breakable art, and there are also 2 very steep staircases. Our kids were able to 'not touch', and we used a traveling baby gear company to rent stair gates and were fine, but like I said it might be more ideal for couples or families with older kids.
All in all, it was an excellent vacation and I recommend the museum house and Hans with 5 stars!
