We had a great time here!
Shawna and her family made us feel super welcome. Shawna even gave us great directions to reach the Backroom from the airport which were really helpful. (Getting here from the airport is super easy. One bus, that's it, and the bus stop is easy to find)
This place is unique and really nice. It is not a 5-star luxury hotel, and that is what makes it so great. The bathroom is a little small, but regardless the space is well appointed (the bed is really comfy, I slept great). The bathroom maybe could be a little cold some mornings, but the place as a whole warms quickly and holds heat well. There is no TV but the wifi works great so you could maybe stream TV but really, there is so much to see in Amsterdam just outside the door that you shouldn't need TV.
The Backroom is at the back (separate) from the rest of the house, away from the hustle and bustle of the busy (and awesome) street. Being at the back of the house means it is quiet and calm at night. The location is great, it is close to so many things.
I would definitely like to stay there again!
