The apartment is very well located, within 8 minutes of walking from Plaza de Sol. It is close to a subway station and to several bus stops.
The host Andrea was very nice and we communicated very well.
The sound proofing between the rooms is very poor, so people sensitive to noise might have problems sleeping.
The TV in the living room was not working. This was not a huge problem, though we would have liked to watch the football game one evening.
I recommend this apartment to those who want to visit Madrid.
