Oscar & Vanessa have a very modern flat, close to museums and metro stations. Their friend Anibel checked us in, so we never met our hosts. However Vanessa was quick to answer any questions we had by email. We ate at the Hanakura restaurant right next door twice, great food and very friendly service. The street sounds can get noisy in the early morning with garbage trucks, but mostly a quiet neighborhood. Be aware there are 4 flights of stairs to the flat (no elevator) and bring a flashlight if you return late at night. Highly recommend.
