Oscar's house is very beautiful, clean and in a great location to explore Madrid. We came to Madrid with a medium level of Spanish and had to rent an apartment for our stay (one year) which is a daunting task having just arrived in a new country for the first time. Oscar was incredibly helpful in answering all our questions about Madrid, it's different barrios, customs, and cultural events. He speaks slowly and forgivingly in Spanish which encouraged us to practice and gave us the confidence to speak to more people, including his lovely son Ahmed who was also in the house. The house is kept very clean and is in a beautiful area on the edge of Vallecas, close to a great ecological coffee shop and Panaderia (se llama Yaya), as well as a great mountain where you can watch the sunset over the city and see some locals playing futsal by the highrises. I would highly recommend Oscar's house to anyone. Superhost!
