We had a perfect stay at Aaron's place! Even though Aaron was not at home during our visit since he was in Thailand, he was very helpful through email communication and arranged everything perfectly for us to come to his home. His father welcomed us and he was extremely polite, helpful and sweet to us during our stay. The apartment was very clean, close to the metro and isolated from any noise. When I come back to Madrid, I will definitely look up Aaron again. I would recommend his place to anyone. Thank you!
