Jon is a really great guy to deal with, and the apartment was exactly as we hoped, super clean and tidy with a spacious and bright main room, even more so actually with AC both powerful and silent, and flawless broadband internet connection (very welcome).
The neighborhood is very nice, a paradise of eating spots with a metro station nearby, at walking distance from the Ramblas. What we really loved was its location at the foot of Montjuic: a 5 min walking in the morning and you can have breakfast surrounded by its gardens with a fantastic view of Barcelona.
We loved our stay so much that we ended up extending it to another 4 days!
