This is such a cool place to stay in Barcelona. The design is great and having a little outdoor space is so nice. The neighborhood is much more local that tourist. The beaches are so relaxing and full of locals enjoying themselves. The Poblenou ramblas are a short walk away with lots of options for food and drink, a great place to wind down after a long day of sightseeing. The metro stop is very close and only ten minutes into the center with no transfer. I 100% recommend Rut's place. She is very helpful with anything you may need and checks in to be sure you are happy.
The only caveat I can think of is that it is a very bright space. If you're the kind of person that wants blackout curtains and sleeps in late it may not work as well for you. Otherwise it is very comfortable and unique place in a perfect neighborhood for enjoying the local vibe.
