We stayed in the flat for about 5 days and it was the most pleasant stay. José met us in person and showed us everything about the apartment and parking. The apartment is just as described and more - the bathrooms, air-conditioners in every room - handy on sunny days, great kitchen with lots of space and tools.
It will take about 30 min to get to the center of the city, and only 5 to get to the beach. We didn't use transport - just walked slowly through the city-)
I would say that the building is located in a pretty busy area, but the apartment is soundproofed very well, so you won't notice, but will get all the perks - there are lots of restaurants, bars, and bakery near the apartment. José gave us directions for the main attraction of the city (don't hesitate about "automobile and fashion museum" - that's a gem!)
José is very responsive and friendly, he is a great host and I really recommend his flat!
