I LOVED staying at Carolina's place. The recent renovations were great and the space was even more charming than I anticipated! The location is fantastic (pedestrian-only) alley with LOTS to do near by! Carolina was a great host who was responsive to all my questions. I'd love to stay again if I return to Barcelona!
My only note is that the entryway and building stairs are VERY narrow - you will need to take caution with your luggage. I had a slightly overstuffed carryon and found it a bit cumbersome- luckily, you only have to really worry about it at arrival and departure!
