Carolina and Tico's place is great - they gave us a very warm welcome and had thought about all the little touches - maps, water in the fridge, toiletries, etc. - and the apartment was easily large enough for two of us. The main positive about the apartment though is undoubtedly the location - it's within walking distance of many things (Picasso Museum, Cathedral, Barceloneta beach) and has many great bars and restaurants on the doorstep. The apartment is also just off a main road and therefore hailing a taxi is easy if needing to travel longer distances. Would highly recommend this place!
