It is a very nice flat in a safe neighbourood. It is basically located in the middle of everything so I did not need to take the metro to move around the city.
The pictures are exactly as showed on the website.
I have only met Carlos who was very nice and showed me everything I needed to know. The only problems were that the internet doesn't work and there is no air conditionning but Carlos told me about it so I knew what to expect. Also, I would suggest people to get ear plugs as you can hear everything the neighbours do.
I would definitely recommand this place and even come back if I ever happen to be in Madrid again.
