We had a very nice experience staying at Arina's. A short walk to CCIB (~10 mins) with a possible pleasant detour along the beach (~15 mins to CCIB). Apartment to beach is a 5 min walk. Easy restaurants, cafes and convenience stores all within a short walk. 10 min walk to one end of Las Ramblas. Coordinating check-in was easy and Arina was nice to ask how our stay was going, although we were not in need of anything. We were there for a conference at CCIB and I would definitely recommend this as a place to stay for someone doing the same.
