In hindsight the stay was ok at the most, not as expected though.
It wasn't clear to me at all what was going on in the apartment and how many people were there at the same time (also sharing the same tiny bathroom). I met at least 4 different people in the hallway and there was no heads-up from the host in advance. It seemed a little mysterious and nobody cleared that up, so naturally the noise level was a bit disturbing at times.
The bathroom had a lack of cleanliness (mostly hair, grime and stains), especially in the sink and toilet (where the seat was very very loose). And the smell was nauseating most of the time, but that's no wonder with 4 or 5 people using it instead of 2.
Host didn't respond to doorbell or phone call or email when I arrived, so I had to wait around 15/20 minutes in the heat. also another time when I got back and couldn't open the door with my key, I called her with no response whatsoever.
So all in all the location was very convenient with a max 5 minutes walk to the metro station and the room I slept in was quite clean and the after asking the host even provided towels.
But I felt really uncomfortable in the bathroom and during the time I actually spent inside, because of the unknown number of people (I guess it was her friends or family, but still...) and the lack of communication and response.
In conclusion the price was clearly to high for what I got in the end. Could have been better with a little more communication and cleanliness after all.
