Natalie and Javier are wonderful people and awesome hosts; even though we didn't get to spend much time with them, as we were gone all day, they made a great impression on us when we had a long chat one evening; they were quick to answer any questions we had, we communicated easily via sms/whatsapp , they are so quiet, you don't even know they're there:) We found their place very easily - we ubered from the airport, but you can also get there with the flyaway bus and then one subway station. Their home is very clean and cozy, you have a wonderful room and easy access to the kitchen and bathroom(even though it was a shared bathroom, it was always very clean). Overall we had a lovely stay and I definitely recommend staying there!
