We stayed for 3 months in Marta's apartment and felt very much at home and well taken care of. The space is comfortable and well provisioned; we had everything we needed. It's a great location--a quieter neighborhood with tree-lined streets, but close to the subway and a few blocks from a nice city park (3 de febrero). And Marta is the hostess everyone wants to have. She was kind, accommodating, and quick to respond to all our requests. When maintenance issues came up (all of them minor) she had them taken care of right away. We didn't meet Marta in person, but both Gladys and Walter, who live in the building and worked with Marta to take care of many things for us, were also all-around friendly, competent and available. Very recommended!
