Communication with Salvador was very easy throughout. Things ran a little late at the airport but Salvador kindly waited for me. As for the flat, my native DF friends were floored by the location and size so I think I don't need to say more on those topics. Everything in the flat worked perfectly and the people in the building were very nice too (very sweet doorman). Even though the area is bustling, I was never disturbed by noise from the street at all. The flat is very safe and comfortable. Overall, very enjoyable experience and would come back to Salvaor's for my next visit. Thanks, Salvador!
