I stayed only two days in Buenos Aires, but you can tell that Martin knows how to receive a guest. The instructions to enter the building were very clear, with videos showing everything. Martin and his wife couldn't receive me, but were always available to answer any questions since the moment I made the reservation. The place is bigger than it looks in the pictures. Everything was very clean and tidy. The bathroom is great with an excellent shower. The kitchen has everything. The bed is also very comfortable and the air-conditioning works great. The building is strategically located to visit a lot of the main attraction in Buenos Aires (5 minutes walk to Puerto Madero) and it's near a lot of transportation options. There are markets, pharmacies and restaurants very nearby too, everything within walking distance. Highly recomended!!
