The flat has an excellent location. They and the doorman were amazing and responded to all our requests really swiftly and politely. The apartment could do with a fresh coat of paint (something we recommended to the owners).
But everything worked fine.
If you leave in a quiet area ear plugs are highly recommended (Buenos Aires is a noisy city and you might get an odd ambulance plus honking- never as bad as in India). I should clarify here that although the flat is in a busy avenue there are no bars or nightclubs nearby. Towards Livertaror you come into a really nice area. There are lots of lovely ice cream shops and restaurants near by.
