We had a lovely stay. The location was perfect for us. Very close to the beach and in a safe neighborhood. We were close to the Metro and bus stations.
The apartment was accurately described. It would be quite small for 4 but worked well for two and we had 3 for a few nights. There was street noise all night long but you are on a main road in the city so it is to be expected and a little white noise inside does the trick.
Jane was a lovely host. She accommodated our early check-in request, provided beverage and snacks and left the kitchen well stocked for cooking if you choose. She also was kind to arrange a middle of the night taxi for our departure. A great value for our week in Barcelona.
