I had one night here in a deluxe room. The room was on the ground floor so it was quite noisy. I was also told by other people that I should bring ear plugs, since the walls there are pretty thin. It is a nice hotel, the staff was friendly but I would recommend asking for a room on a higher floor if you want to stay here, or bring some ear plugs. Also, check out is at 11 o'clock, which is one hour earlier than usual. If you wish to delay checkout they charge 10 euros per hour. You also have to pay a city tax when you check out, which is a few euros.
The location is very nice. It is surrounded by beautiful nature - perfect for a long walk. Also it is quite close to the buss stop that takes you to and from Utrecht city centre.
