We really liked our stay at the Barbara place. We were there for one week and had everything we needed.
The location is just perfect. One can walk practically to all main attractions.
The building has a security attendant at ground floor. Internet connection was fast.
We did not have any problems at all during the stay. Barbara, the hostess, was very attentive when we needed her advise on the day of departure due to streets closure because of the celebrations after Argentina victory in the Football World Cup.
When we come with another visit we would definitely try to get this apartment again. Price/quality ratio is very good.
