My family and I loved staying in Cris' flat. It is really stylish and because the space is well organised it felt much more spacious than I thought it would and we did not feel crowded. In terms of facilities great to have a small room with washing machine and where you can dry things (especially after beach days) or store suitcases.
There was no balcony but actually if you opened the big windows in living room it felt much like a balcony with lovely views (you don't see this on the pics website but view across is a lovely old stoned hotel or house and hills in the distance).
If you are not driving or just want to avoid a car the beach buses for Sa Riera and Sa Tuna are literally down the road (quite frequent, cheap, 15 minutes or so ride). Also the walking path to Sa Riera starts after the park at the bottom of the road. The park has children playground but also basketball and football. Our kids loved it. Very handy (has picnic tables too - cafe and public toilets) and stylish.
If you walk up from the flat you are straight in all of Begur's most charming areas, cafes etc...Personnally not having a car we loved that. With the convenience of it I would definitely stay longer if we are able to go to Begur again.
