The place was amazing: very large appartment and great service. Even in 35 degree heat the appartment kept very cool and was really comfortable to stay in. (We were four people and a dog) Would definitely come back here in a future trip to Gallipoli! The old town is extremely charming by the way, would recommend this to everyone.
The only thing to be aware of is that due to small streets of the old town as well as numerous old minivans selling/shouting products early in the morning, it tends to be very loud. This is the case in the whole town though and has nothing to do with the appartment. Just something to be aware of if you like sleeping in as this kept us up a lot :).
