Overall the stay was good. The location was amazing, but the listing pictures weren't fully true to form. I read about some things to watch out for in the comments, so I'll echo a few:
1) Internet. The internet was not good at all. unstable and very low speeds. The host had a a 4G mifi router in the flat (a basement apartment) which isn't good enough.
2) Room Privacy and Layout. For privacy and to sleep well, there are only 2 usable beds. The top feature of the apartment is the upstairs bed. However, that's not walled off from the rest of the apartment (so no internal privacy) and it's at the ground floor level for 2 other apartments (no external privacy as you're looking into the neighbors' living room). I hope the listing is updated with more full shot images to show the house layout, and that the actual layout is drawn out.
Also, it is a basement apartment, so be ready to carry a few things.
With all that being said, it was a good stay in a very well located flat. I personally wouldn't do it again just because of the rooms layout and the darkness you get in a basement flat.
