Ruben was a fantastic host, and we had a great time during our stay. The place is simple and clean, and it's outside the busy city center in a quiet and relaxing neighborhood. It takes about 10 minutes to walk to the metro, which you can use to get anywhere in the city. There's also a night bus that goes near his place after the metro is closed. Ruben is a helpful and friendly host, and I'm glad we had the chance to meet!
