We stayed in Barcelona the days of the referendum for independence in 2017 and the demonstration afterwards and Sylvie was a great source of information and a great help when we needed to get to the airport while a general strike was going on!
She also gave us great tips for sightseeing and eating out and one got the feeling that she is genuinely interested in her guests (without being intrusive). Apart from that, the place is very clean, very cozy, quiet with closed windows, perfectly located and you can darken the windows completely.
Next time when in Barcelona I would love to stay there again!
