Ángel was very friendly and every now and then made sure I was comfortable and not having any problems. He was very smart and able to find a solution when I made a mistake with the booking dates. He also showed me how the washing machine worked. If he had a request for me or wanted to consult with me/invite me before he and his flatmates were going to be doing something in the apartment (like a party or a meal out on the terrace), he or Álvaro (who is also incredibly nice) always asked me first. They have great suggestions for nearby museums and restaurants to visit. In short, those two guys are really great and helpful! Oh, and their little dog is such a sweetheart!
The apartment itself was mostly what the listing described. While the kitchen floor was a bit dirty, the bed was a tad uncomfortable, and a few bugs snuck into my bedroom, none of this bothered me much. The only thing I might recommend is a higher quality mattress. On the other hand, it's a great place to have parties, because 2 DJs live there already! :)
