Martin´s place is a great choice for either a short stay or longer stay in Buenos Aires. The location is perfect for those visiting the town for the first time as it is within walking distance to the main touristic attractions (Casa Rosada, Puerto Madero, etc), the main road and the underground. The apartment is really comfortable and, most important for me, very quiet as it is at the back of an old style building in San Telmo. You can easily cook there as the apartment has a good range of appliances and relax after a day out and about. A bottle of wine was there waiting for me when I arrived as a nice gesture and an interesting collection of music to listen to as well. I believe the flat would benefit from a better internet (the connection was lost for a few hours during two days of my stay) and, for me, a better bed, as the mattress was too soft for my liking. But those two little things did not taint the good experience and I would definitely recommend Martins place or stay there again.
