Our stay at Mercedes's apartment was totally delightful. It's super clean, well-stocked with amenities, and modern but with old-school Spanish touches like the tile floors and shutters. We had coffee or wine on the terrace every day, walked the few short blocks to the amazing beach a couple of times, and just generally felt at home. Mercedes was super sweet at check in and out, and very understanding when we had an unfortunate hot chocolate spillage incident. She provided beach towels, a beach umbrella, bags for grocery shopping, laundry soap--all we had to do was enjoy ourselves.
We are two adults and two teens, so the second bathroom was a plus. The beds are super comfy, and one of our kids slept in the living area on the couch and reported that it was great. There are sliding panel doors that close off that area and make it feel like a separate room at night. It was extremely hot the week we were there, so the central AC was really nice to come home to.
El Poblenou is a great, quirky neighborhood with tons of restaurants, shops, and creative businesses. The apartment is in a quiet section but just a short walk to the very lively neighborhood rambla. It's easy to take the metro into the city center too. Truly, we couldn't have been happier with the choice to stay at Mercedes's place!
