We had 13 travelers and there was plenty of room for everyone, for sleeping and for lounging around at the end of long days sight seeing. The photos of the place do not do it justice, there is a lot of room and the place if very well decorated, it kind of feels like you are staying in a museum.
We were provided lots of keys, so each group had a way in and out, which was also great compared to other places. The host was also very helpful in arranging for transportation to the train station two times.
The location was perfect. Across from a museum, but really at the edge of the crowded areas, but still walking distance to everything. Several wonderful places to eat right on the street below. And the views outside the front windows are wonderful. The beds were good and the house very comfortable. Overall we loved our stay, but there were a few issues or things to be aware of.
1. "WIFI in every room of the house" is not accurate. Wifi only worked if you were close to the router. Once you go down the hall towards the bedrooms, the signal is lost. Not a huge deal breaker, as we were there to sight see, not stay in, but WIFI is a must for most to avoid large cell phone fees.
2. "Check yourself in with the smartlock" is not accurate. You must be checked in by the host and you have to sign a separate rental agreement, outside the AirBnB agreements. This should be noted when making reservations, not when you get there, because now you have no choice or be left without a place to stay. I was not comfortable with this separate rental agreement, but felt we really had no choice but to sign it.
3. There are not shower curtains, so water get everywhere in the bathrooms with bath tub/shower combos. Additionally one of the shower doors was broken when we arrived, and the only response from the host was "dear guest, very sorry for the inconvenience"
