Everything was great! The apartment is very cozy and private, indeed. Jaime was there to greet us and show us around just as we had agreed. Since we didn't really need any help after that, he respected our privacy and left us to our bearings. The neighborhood is cool and many points of interest are close by. The only slight inconvenience is that the closest metro stop is a ~15min walk away but there are many parks, coffee places, food stands, and restaurants on the way.
Greatly recommended!
