This place was absolutely perfect. Checking in was very simple and the apartment was very clean. The reception downstairs is manned 24/7 and the host is very responsive if you message with a question or problem.
The location is fantastic, we were able to walk to many of Buenos Aires' famous buildings and wandering down along Puerto Madero at night was great fun. Also, the train station is only a few blocks away if you plan to venture a little further afield!
Oh, and the bed was very comfortable and the shower had great pressure and plenty of hot water!
