The place it is well located and it was clean. The lady helping the host is nice.
Some items are not mentioned in the ad, though. The window leads onto an indoor building corridor, and the unit is on ground floor. So light and ventilation are hard to get. It can get noisy too with people walking through and garbage traffic.
Also, the washing machine did not work, the host knew beforehand, and did not feel much intention to fix it. Was offered lining exchange instead, and I got partial refund through arbitration.
The TV did not work either, but maybe it was just me.
The auxiliar mattress is comfy enough but not the main one, it sinks.
In rainy days would get super wet, even through the floor up.
It is a good deal compared to market prices if you do not want to share, but still find it pricey for what it is.
I believe it is a good place for a short stay if you are planning to enjoy Madrid, but not for medium/long.
