It is a lovely and warm place to stay. The location is great, with the beach and many famous sights within walking distance! The place is also very easy to find (and I think that's because Lola will explain it to you in greaaaaaaat detail! You can hardly get lost with her guidance >. <)
Lola is a perfect hoster!
She gave me a clear introduction to the whole house at the beginning and for the rest of my stay she was very respectful of my privacy and would not enter my room without my permission.
But if you do need her to solve some problems, she was always there, giving you quick and helpful reply!
I extremely recommend this place if you are travelling alone to Barça!
