Pros:
--Neighborhood is amazing, right in the center of everything. My partner and I felt very safe and there were so many great restaurants nearby! Go to El Copetin for tasty cocktails and (very tight squeezed, but fun!) dancing. The arepas restaurant around the corner is magnificent and great tapas are literally everywhere.
--Maria was super responsive via email before our stay. She ended up needing to leave town on business, but her friend Lua, the replacement host was absolutely fantastic. Kept the place well-stocked with essentials like clean sheets/towels and toilet paper. He also gave us a great recommendation for paella at El Gallito -- one of the best meals I've had in a long time.
--I loved the list of recommendations for places to go and safety tips for navigating Barcelona that Maria provides every guest.
-- The room had ample storage space for how small it was.

Cons:
-- The apartment is much darker and smaller in the living room and the small room than it appears in the pictures.
--The smaller room was a bit tight for two people. It can get pretty warm in the room, but there is a fan provided. I was comfortable with it, but the fan was a little loud for my partner to sleep next to.
--The shower temperature is finicky (too hot or too cold), but that's pretty normal for an old building.

Overall, I would recommend this room more for a solo traveller looking for a place to crash while exploring Barcelona. Try to book one of the exterior facing rooms in the apartment if you're coming with a partner.
