If you are coming to Buenos Aires do yourself a BIG FAVOR and stay at Rosa's. There are many many modern rental apartments in BA. DO NOT STAY IN THEM. We went to visit other friends staying in an apartment like that and after we left we both said that we were so happy we didn't stay in that kind of place. It felt like it could have been anywhere in the world, not anyplace specific. So do not stay in a white box!!!! San Telmo/Monserrat is the perfect location. You completely feel like you are really in what makes Buenos Aires unique. It's the oldest part of the city. Many Many beautiful buildings. And now about Rosa.... She is soooooo warm, friendly, accommodating and helpful. She lives in another apartment on the same floor. She gives you total privacy, BUT if you need anything she is right there on the same floor. We live in NYC so for us the apartment was giant! :-). AND the apartment itself is so beautiful!! It is decorated with a personal vision. Rosa designs textiles and many of the textiles in the apartment are her designs. The apartment is as far away from a boring white box as you can get. All of the elements in it are wonderful.
