Roberto's house is just as described. Cosy studio appartment near the bus and train station. Communication was flawless, and Roberto picked us up at the train station on arrival.
The neighbourhood and building can look a bit sketchy but it was safe to walk around, even at night.
Cleanliness was perfect.
The only thing that happened to us was that if you tried to cook with the electric stove, it was ok for a few minutes and then electricity went off. If you didn't use the stove and switched back the electrical panel, everything was working again. Must be an overcharge in the system, otherwise everything was fully functional.
Overall prize/comfort/location is greatly recommended.
