We stayed here between Christmas and New Year with our two young children (18 months and 5 years). Rosa is a brilliant host and always quick to respond to any messages. She met us when we arrived to show us the apartment, as well as give lots of useful tips on things to do and how to get around. She also kindly provided a few toys for the children.
The flat is in a great location, just a couple of minutes walk from a sandy beach, restaurants and marina. The main sights of Barcelona can alsobeasily be reached by foot or bus. There are also lots of shops and a great bakery near by. The flat is well stocked with beach toys and towels which were really handy.
I would definitely recommend to anyone visiting Barcelona.
