I stayed here in May with my mother and aunt (both discerning women in their 60s) and my cousin. We loved Nacho's house and Begur. Such a sweet and quiet town, but still plenty to do. The house was a good size for our party of four adults but easily could have held more people (as long as you don't mind sharing a bathroom). Everything worked perfectly (wifi, washer, coffee maker, hot water in the shower). The house is decorated like for a real family and we felt very welcomed by Nacho - he met us to show us the way by car and had wine and cheese ready! The street is small and very quiet and a little steep; we opted to park in one of the nearby public parking lots, as Nacho recommended. Not too far a walk and easy to find a spot in early May. Short drives (or a bit of a downhill walk) to beautiful beaches, and walk to several nice restaurants (or anywhere) in Begur.
If you are looking for a low-key place to call home as you explore the Costa Brava, we couldn't recommend Nacho's place more.
