The location of Sylvie's place is so central that you can get to La Boqueria in a 5 minute walk, Las Ramblas shortly after. Plaça Catalunya is only 5 minutes after that.
The place is is spacious and internet is fast! Sylvie stays there too and she's such a HUGE help! Even made dinner reservations for us! She's extremely nice and is always willing to help!
Highly recommend Sylvie's place! It'll make your trip 10x better!
