Clean, modern, and simple but extremely well-organized very cute studio. Ideal for me (single woman - 60), and would be fine for a couple (if they really liked each other.) The building is nondescript, and a bit shabby in the halls and stairways, so it is not a great first impression. But I found the place to be an oasis for the 6 weeks I stayed there.
The apartment is reasonably appointed for self-sufficiency, but as someone who was there for a big chunk of time, and loves to cook - it could have used a bit more basic cookware. But I found it to be workable nonetheless.
I found Rossella and Martin's team to be very responsive and accommodating in our communication and resolution of any questions that came up.
I felt the neighborhood to be extremely safe, despite the warnings I've read about El Raval/Sant Antoni. At my age, and as a woman traveling alone - (as as obviously a member of a vulnerable demographic), the area was perfect. Local, but close to the tourist stuff (Rambla, Markets, are really close. Barceloneta Beach is about a 30 min walk.Place de Catalunya and especially the Gothic Quarter are less than a mile away). Riera Alta is a bustling and diverse neighborhood. And IMO, much closer to how it would feel to live in Barcelona as opposed to vacationing there. You need a bit of big city "street smarts", and not walk around with your phone in your hand, back pocket, etc).
There are tons of restaurants, food markets, antique and clothing stores and the area is alive with the day to day of Barcelona - although the weekend nights on the street could be a little noisy. This was not too much of a problem, because the apartment sits at the back of the building and I found it to be pretty quiet most of the time.
Tip: If you forage for all kinds of produce and fruit, it is easy to get an unusual amount fruit flies (barcelona humidity?) around the stuff you leave out. FYI...A cup of cider vinegar, with a few drops of dish soap, and a teaspoon of honey makes an excellent trap...
Overall, I would definitely stay here again, and probably will in the future. It's a great little find and the attention to design details and appointments - and the location - made it absolutely perfect for me.
