We had an excellent stay with Òscar. We were looking for a quiet retreat on the Costa Brava and this was it! The location was perfect for us (though it is about a 15-20 minute walk into town, depending on where you want to go). We loved the old town of Begur and were able to take the town bus to and from all the beaches in the area. (Tip: If you visit the tourist office in town you can get a value pack of 20 bus tickets for .70 cents each instead of the 1 euro they will charge on the bus - with a savings of 6 euro total).
The flat itself is really well stocked. It had everything we needed (small sitting area, balcony overlooking the mountains/sea, kitchen, bathroom and bedroom). There is no A/C but the breeze is all you need.
Òscar is incredibly helpful and responsive. He is ready to help at any time and was even kind enough to drive us to the bus station when we checked out. (Note: He speaks limited but effective English).
