My stay at Rubén's was very pleasant.
The apartment couldn't be situated at a better location. It is right in the heart of Madrid, the wonderful neighbourhood of Chueca. Literally a heartbeat away from supermarkets, shops, metro stations, bars, etc.
The room might be small, but it's comfy and equipped with a comfortable bed, an a/c (ideal for those hot summer days), a small wardrobe and a telly.
Jaime was an excellent host, warm, kind, and always there for a quick chat or to offer any help you might need (unfortunately, I didn't get to meet Rubén or their sweet dog, Nara, in person).
The only thing that you might want to keep in mind is that there is no elevator in the building that leads to the apartment, just a flight of stairs, so if you are carrying a lot of luggage, prepare for a tiny bit of weight lifting (thankfully, Jaime helped me with mine).
Jaime, Rubén, les agradezco por todo. La pequeña Stella y yo les mandamos un abrazo!
