PROS:
-Mariano is easy to communicate with and very quick in his responses. I had a problem with the apartment which led me to leave early and he handled it very quickly, which I appreciated.
-Check in is very seamless.
-The apartment is located in the La Latina barrio of Madrid. Check to see if this location is desirable for you. If it is, you will be content here. If not, it still is fairly close either by walking or metro to various other parts of the city (depending on where you want to travel to...check the map).
-The La Latina metro line is about a 5 minute walk from the apartment & Tirso de Molina metro line right around the corner.
-There is also a grocery store around the corner & an organic market not too far either.
-I found the bed to be comfortable and the bedroom is quiet, as it is far from the street
CONS
-Mainly for me, the main con was that the air conditioner was not working during my stay so I had to cut my stay here short. In August in Madrid it is quite hot, and I could not cool the apartment less than 28 degrees C/~84 degrees F & the bedroom itself was probably hotter than this and it seems to cool less efficiently. This was undesirable, as I booked the apartment because I saw it had air con as an amenity. The night and trying to sleep were particularly difficult. Further, one is not allowed to use the air con in the night. It is noted that this is according to Madrid regulations, however, I did not come across this regulation in the other apartments I stayed in. Obviously during the rest of the year, this is not an issue, but be aware in the heat of the summer.
-Not necessarily a con for all, but this is not necessarily a private room in a shared space... it is likely an "entire apartment" stay. Another reason I booked here is because I was hoping to not be alone. You might desire this though!
