We loved Tom's place. Tom wasn't in Buenos Aires but he had the lovely couple, Raul and Noemi take care of us while we were there for 2 weeks. His place is in the heart of San Telmo, where everything you need culturally in Buenos Aires is found. We needed a comfortable place to stay and Tom's place delivered. There were days that we didn't want to go out and eat so we did our groceries from a nearby supermarket, and cooked in his fully equipped kitchen. His Internet was also fast enough to watch Netflix shows. The subway (SUBTE) is only a few blocks away. Casa Rosada is not too far either. Overall, can't recommend this place enough.
