Rosario is an excellent host. He met at upon arrival and helped with the parking, he gave good recommendations for restaurants, museums and the best walking routes to take from one place to another. He responded within minutes to any questions and requests. I've never had such welcoming host taking such good care of his guests.
We also like the neighborhood. It's residential, but very close to the center, nice, safe and quite. It was perfect for us.
The only 2 problems with the apartment is the size of boiler and luck of proper heating system. The boiler is small. If you shower quickly it's hopefully enough for 2 people. The only source of hit is air-conditioning unit in the kitchen, so again it's barely effects the temperature in the bedroom.
It's quite possible that in summer, these both problems don't even exists unlike during our stay in a rainy week in winter.
Overall we had a good stay. Thank you, Rosario.
