I spend four nights here with my 8 year old son in Sep -18. The place was clean and there were lots of guidebooks and tips on what to do and where to eat in the area.
Great beds, pillows, towels and bedlinen. Nespressomachine was much appreciated! It was amazing to get to pass sagrada familia everytime we went to/from the Metro and there were many nice restaurants in the surrounding area.
It was a big Holiday when we were there, La Merce’, which offered loads of fun all over town, unfortunatly it was probably also the reason for noice from late family dinners and gettogeathers in the house. If I had been there with friends to stay out all night it would have been fine but it got quite hard for me to sleep. Noone seems to have mentioned noice from neighbours or traffic (even when the windows were shut) so maybe I’m more sensitive to that than most.
But, if you know that you are sensitive too, maybe choose a different place :)
