This flat was one of the best I've ever stayed in. It was bigger and much nicer than we thought it would be. This is a seriously fantastic flat. I do believe this flat is "undersold" in the listing. It is better than what is described in the listing.
One consideration for those renting this flat is "neighbor disturbance". Two times in one night neighbors knocked on the door and complained we were being too loud. One event only one person was home where she was watching a movie in bed on her iPad around 22:30. Somehow an iPad was too loud.
The second time, 4 people were in the house listening to music on a speaker a the size of a deck of paying cards. 3 others were sleeping in the flat. None of those sleeping were disturbed yet the neighbor came down and told us to be quiet. In the flat, the music was far from loud. You could not hear it outside of the immediate vicinity of the speaker.
Our group is not one to "house party and get loud". Be cautious in this flat as I suspect the acoustics of this place simply magnifies to the floor(s) above.
If you do play music or converse at a "neighbor sensitive" but reasonable level, this flat is not for you.
