We had a lovely stay at the apartment - exactly as described and in a fantastic location for exploring the beautiful city and very close to the lively Biarra Alto area. Luis was also excellent at communicating with us before and during our stay.
Whilst it didn't detract from our enjoyment, there was quite bizarrely TV filming taking place in the apartment below during our whole stay. I imagine this was a one-off, although it did mean there were lots of people coming and going from the block. That said, I would definitely recommend staying here.
