I'm loathe to write a review because others will now book this place as well and I want to keep it a secret so we can book it again. But it's a lovely hideaway and Eva and Sebastiano deserve recognition as great hosts.
Like other reviewers, we also had the place to ourselves - and it has a beautiful little garden and a pool that's actually bigger than it seems in the pictures, and where we enjoyed swimming and relaxing. It seems the family only rents the flat out when they are not there, so there is great privacy.
The flat is actually below the main house and garden, sort of at basement level, but given the heat in Italy (even in May) this is actually a benefit. It has its own outside dining area, two good size rooms and a bathroom. The kitchen is, slightly unusually, separate to the flat and struck us as small when we arrived, but turned out to be perfectly adequate, even though we were eating in every night. Plus we were able to use the great barbecue.
Location-wise it's terrific - a really short drive to beautiful Lecce, Nardo, Galantina and Gallipoli and only about 40 minutes across to Otranto. The nearest beach towns of Santa Catarina and Santa Maria Al Bagno are technically in walking distance, though we usually drove. The road it's on is full of curiously glam and grand villas, so the location has the slight feel of an Italian Beverley Hills.
Anyway, if you're looking for a peaceful hideaway, with easy trips to beautiful towns and beaches nearby, it's fantastic.
