Apartment is in a great location and is accurately described. Martin was a welcome and helpful host. Martin's aunt was also wonderful and inviting and they were both really great in helping me store and retrieve my luggage after check out on the last day.
Unfortunately, I had a lot of problems with the internet connectivity. Martin was really responsive in contacting the internet service provider and getting it back up and running twice.
This apartment is in a great location for exploring Palermo on foot and other areas via public transport. The subway is close by and easy to use, the buses are everywhere but harder to figure out. I recommend visitors get a street map with the subway network shown on it (available from tourist info offices in the centre of the city) and buy the Guia T (guide to buses) from the newspaper stand. It was a little tricky to figure out how/where to catch the bus without that.
Buenos Aires is a wonderful city with wonderful people - I highly recommend both it and this apartment.
