We visited Madrid for a few days with my girlfriend and my mom. We decided to rent Ruben's apartment because it was very conveniently located and had everything we were looking for (including separate rooms for my mom & us and an elevator in the building). The location is very nice, right next to Plaza Mayor and with lots of shops, restaurants and bars very close by. On the street side it can be a bit noisy with the crowd below but when you close the doors it's much quieter. The flat was well equipped and comfortable. We just met Ruben on arrival since our flight back was early, but we were messaging a bit during the stay too. He's a very friendly and helpful guy.
