Carlos' place is a great option for staying in Madrid and we highly recommend it. Lavapies is a great neighborhood: easy walk to all the sights in the City Center as well as museums like Reina Sofia, but also a fascinating mix of long-term residents, new immigrants, street art, cafes. The apartment is compact, but plenty comfortable. As a host, Carlos is super responsive and he has added many thoughtful, welcoming touches. We would definitely stay here again. Thanks!
