A bright, clean and well equipped 2-bedroom apartment, can easily accommodate 4. There is a sofa bed in the living room, which could accommodate 1 or 2 more guests. But that'll be rather cramped as the living room is small.
There are lot of restaurants nearby. A supermarket is about 150 meters away. The location isn't ideal if you plan to spend lots of time in the city (bus stops are just around the corner though). But if you're attending conferences at CCIB, it's only about 10 minutes walk. The beach is also very close.
Pau, the host, is fabulous. He is always responsive. After checking-in we realized that the 2nd bed wasn't prepared due to some misunderstanding and we couldn't find any provisions to do it ourselves, he came straightaway to have it prepared.
