Diego was very responsive to our questions before and during our stay.
José María and his wife picked us up at the airport for 25 Euros. I was hoping to send them the 25 Euros through AirBNB because it was my last night in Europe before returning to the US and I had spent almost all of my cash. This meant a search for an ATM after we put our bags in the apartment and José María showed us around.
The apartment was nicely appointed and roomy, though some of the amenities were lacking.
The neighborhood was safe and quiet and a few blocks from a Metro stop and some adequate restaurants.
All in all, a very nice stay.
