We felt like we got very lucky with Che Telmo. It's clean, quiet and safe, and in a great location in San Telmo close to the city centre.
The owner Mario is very very helpful, although he doesn't have the best English he was friendly and welcoming and happy to help us find our way around the city.
We had a triple room, which was simple but clean, although we did have to get used to posters of Che Guevra plastering the walls....
Overall it was great value and a great find - I'd definitely recommend it.
