My son, daughter and I had a wonderful stay in Martin's apartment. He replied to my emails before we arrived and we were met by a friend of his who showed us everything in the apartment. Martin was very flexible about our check-out time, which was extremely helpful.
The apartment looks exactly as it does in the photos. It was clean, modern and felt airy. The apartment is at the back of the building and is quiet. The bed in the bedroom is very comfortable, and so was the pull-out couch. We felt very safe in the neighborhood, which was extremely convenient to every part of Buenos Aires.
The hot water in the shower was a little finicky, but Martin told us the trick is to run the hot water in the kitchen sink first, and that gets the pilot light working better. Doing that worked. We were very comfortable. Everything in the apartment was of a high quality. I would stay there again and recommend it highly.
