I've been in Alberto's apartment for 3 nights and the stay was good. Alberto's apartment is well communicated with the city center and is a good place to stay if you plan to visit the city and only need a place to stay.
It is close to the airport as well what is very handy - just 15 / 20 mins in the bus.
One of the bedrooms blind does not work what was an inconvenience if don't plan to wake up very early.
Does not have washing machine what can be a problem if you're planning a long stay.
We didn't meet Alberto face to face but everything was correct and as agreed.
