Alexandra is a great host. She immediately let us feel at ease while we literaly living with her. She happened to be french (like me) so that was a great asset, it made the communication a lot easier. She was very hospitable. We could use anything in her house: the kitchen to cook, we could use the bathroom whenever we liked. We never felt like we were interfering with her life. We felt very comfortable.
The situation of the apartment is good. We were at a 10 min (steep) walk from park Guell, Hospital San Paul en Sagrada Familia and a 5 min walk from metro station Alfons X. There is a supermarket nearby, a bakery with a lovely lady helping us out and a cafe where we took our breakfast every day.
In short: a very lovely stay for a good quality and price :)
