If you want to be watched 24/7, be seen through a camera in the balcony, be sent a decibel reading screenshot for only talking in the flat, and an overall "big brother is watching you" experience, this is your place.
As people owning or taking care of this flat are over the top with ridiculous precautions, and forget that the point of this is also to provide a nice and enjoyable experience to people visiting the flat.
Other than that the flat is quite nicely furnished, well communicated and a good value compared to other places in Barcelona.
Kind regards
