Sergio's place is excellent, with thoughtful details throughout the flat.
The neighborhood is residential and calm.
The apartment is sparkling clean. Kitchen is very well equipped.
Bed is very confortable, and when you put down the blinds, it is pitch dark for an excellent night's (or day's) rest.
Just on the corner, there is a bus stop with two routes than can take you downtown, and just a 5 minute walk, you may find República Argentina metro station.
Sergio was always attentive to my needs during the stay.
Highly recommendable.
