A very dissapointing stay sadly, for multiple reasons.
The dangerousness of the area is already well established by other commenters. We encountered a huge group of drug addicts right outside the building, sizing us up everytime we walked past them.
The biggest dissapointment comes from the apartment's main selling point, the roof-top balcony. The sunbeds were very dirty and there was nothing blocking the sun, which made the balcony unusable until late in the afternoon. Furthermore, there are hornets flying around - something that the host denied until I mentioned I have pictures.
There is a window looking from the living room straight into the toilet and the shower, so beware of this if you are planning to book with people you are not intimately familiar with!
To add to the awkwardness, there is a huge, human-sized cage in the bedroom.
We had booked the apartment for four nights and vacated it after the first one, even though we were not offered even a partial refund.
