Nice location, spacious apartment, well equipped in a completely new renovated old building (from 1881). Even an elevator is installed. The view is good too - you are on one side facing a courtyard which opens to another historical building.
Residential area - public parking not far away for 11€/day (Largo de Rato). Nice shops and bars in walking distance. Restaurant Pesca is great.
Some room for improvement: Bathroom could use a little more possibilities to put your personal stuff and bed could be a little more comfy.
Check In & Check Out was easy and nice.
I would recommend a stay!
