The BAD:
There is NO AIR CONDITIONING in this apartment even though it is listed as an amenity. There are ceiling fans in each bedroom and a floor fan for the salon/living room. We stayed at the apartment in August and the temperature of the apartment ranged between 28.5 celsius to 30.0 celsius with all the windows open and all the fans going at high speed. Nikolana Y Jose said that AirBnB considers fans as air conditioners. I do NOT consider fans as air conditioning. So far, at every AirBnB I have stayed at, when air conditioners were listed, we had an actual air conditioning unit, with the exception of this apartment. I knew that Madrid would be hot during August, so I specifically booked a place that listed air conditioning as an amenity. I expected air conditioning units, not fans.
One of the doors to the terrace did not open so there was less air flow, which increased the heat in the apartment.
The GOOD:
The location of the apartment is walking distance to many of Madrid's sights. It is also located very close to markets and restaurants. During our stay Aug 11-13, there was a neighborhood festival which was a highlight to our visit. Lots of people, places to eat and drink, carnival type games and loud music. A very lively atmosphere.
The apartment is well decorated, very modern and very roomy. 3 full bathrooms is a plus.
I would recommend Nikolana Y Jose's apartment at any time EXCEPT SUMMER. It is literally too hot in the apartment to be comfortable.
