We rented Mas Sifon in April and May of 2013, and had a wonderful time! Our family of four flew down to Barcelona and rented a pretty dinged up car from Hertz. The drive to Mas Sifon took about two hours on the AP-7 highway. Excellent service on arrival. We immediately fell in love with the house, and especially the view of Canigou, a spectacular mountain to the west. The kids were naturally obsessed with the pool and exploring the rather large, open field around the house itself. Pretty perfect temperature as well, in April-May. Not too hot, not too cool. We had a few days of rain early in April, but spent those shopping in Perpignan or just driving around to get ourselves oriented.
After a week by ourselves, the inlaws dropped by for three weeks. And this is where Mas Sifon really shines; they had their own bedroom and facilities downstairs, while we had everything we needed upstairs. Vacationing with another group is not a problem when both have the option to withdraw for a little privacy now and then. There are several tables around the house to share lunch, but dinners on the roof terrace were soon the norm. Amenities were just right. Well equipped kitchen, effective airconditioning and great beds. Nice and clean pool.
Most mornings one of us took a brisk walk to the nearest bakery to pick up breakfast, and then agreed on an activity for the day. Ceret itself is within walking distance with plenty of sights and experiences. Make sure you check out the modern art museum, the market days and the restaurants clustered around Place des Neuf Jets. And the shop World of Beers (just trust me on this one). Ask for the scenic route to the town, you won't regret it. Another well kept secret; the reservoir lake in St Jean Pla de Corts is about ten minutes by car. Perfect spot for jogging, picnincs and activities for the kids. Evenings were usually spent on the excellent roof terrace.
The best beach is Racou, about half an hour away. Also make sure you visit Collioure and Roses in Spain.
The last couple of days we rented a flat in Barcelona and checked out La Rambla and the Zoo. Two days was not enough, we'll have to go back for a few days next time. And next time, we'll rent Mas Sifon again. Excellent villa, excellent location. Highly recommended!
