The house is wonderful and met all our needs. The kitchen is very well equiped, and all the rooms are large, enough for at least two people each. We were altogether 5 people, so it fit perfectly. Everyone loved it.
A remark on comminucation shall be done, though. Days before my check-in, I suggested to establish a channel for direct communication (Wh@ts@app) with the hosts, but they somehow prefered not to do it.
So when I got in the place to do the check-in, there was this paper on the door demanding a regular phone call to the hosts, so they would let me in. A Wh@ats@pp call wouldn't work.
As a foreigner, I don't have a German cell phone, so I couldn't make the call myself. I had to ask a German friend of mine to make it on my behalf, and I have to say it was very annoying. I had to wait 20 minutes outside the place until someone would let me in, and this surely would not have happened if the Wh@ts@pp channel had been opened in the first place, as I suggested.
Apart this miscommunication during check-in, everything was fine and I would definitely reccomend the house if you have a German phone line, or a friend who does.
