We (me, my partner and our 7 year old son) loved our week in Jaime's apartment! It was perfectly clean, very quiet, felt very safe, and was nicely set up with both rooms opening out onto the patio area. It was very well equipped too - we had everything we needed in the kitchen, plenty of towels (including beach towels), spare blankets and bedding (although not needed due to the great weather!), and even a few beach toys. It is also ideally located being within easy walking distance of the bus stop for the airport and the train station for getting in to Barcelona City, but yet only a few minutes away from the Sant Sebastià beach and the central part of town, and there are a range of shops nearby.
It was also a pleasure to meet Jaime who was very accommodating of our arrival and checking out times, and gave us a very thorough tour around the apartment on arrival as well as some useful tips about good restaurants.
We were sad to leave the apartment and Sitges at the end of our week, and definitely plan to return soon.
