Rosa and Nicolas were excellent hosts. The arranged for a taxi to pick us up at the airport (40€) which was very convenient especially after a long overseas flight. They met us at the apartment exactly on time. No surprises - everything went according to plan.
The apartment was well located and very clean. We were a family of four with 2 older sons and were very comfortable. We especially loved the terrace where we ate breakfast in the morning and enjoyed cocktails while watching the sun set at night. There is a nice view of Montjuic. Close-by are: the subway station, coffee shops, wonderful pastry shops, an arena/Mall where you can get a full 360 view of the city of the roof top (especially important upon arrival to a new city to get your bearings).
Rosa and Nicolas are excellent communicators. I highly recommend them to be your hosts! Bravo!
