This is a nice spot! Very clean and Marie & Peter seem like very pleasant and hospitable people. Great location as well.
The only thing I would add is that I would be careful to read all of the instructions/guidelines they have posted about staying here. I missed the part where they shut the wifi off at midnight (they have an ethernet cable to can use to go wired after midnight if you want) and was rudely interrupted while trying to watch something on my iPad, but that's on me for not paying attention. Also they are morning people and it is probably easier on you and them if you are as well. I'm a bit more nocturnal and after 9pm it felt a bit like I was a teenager sneaking around trying not to wake my parents up.
All in all its a nice room, great location, they seem like sweet and pleasant people, and I had a great weekend. Would recommend with a couple of small and mostly insignificant caveats.
