The first and most important thing to say is LOCATION! It's like living on Portobello Road in London. The market each Sunday is such a blast. Plus hailing a cab is like ten steps off the front door and raise your hand, and getting home simply tell any cab driver the cross streets and they all know the location.
We wanted the experience of living in an older San Telmo apartment, and this didn't disappoint. Safe neighborhood and safe apartment. The rooftop was a blast, even in the winter; we had dinner outside there, and some wine/beers.
The furniture is older, but more than adequate. The kitchen is smaller, but you're living in a city. She hot water heater is smaller, but fine.
Otherwise, we had a BLAST! Tino and Eva were amazing! They responded to every issue we had, and were very generous of their time. Thank you both so much for making our trip so easy.
The internet worked perfectly, which was important for us.
You've got El Zanjon literally across the street - you CAN'T miss this (just make sure you take on of the tours that's in a language you speak), and we had a great night at the El Viejo Almacén around the corner - just get the VIP tango seats but skip the dinner.
For the price, this is a slam dunk five stars.
