Jamie's place is awesome in terms of size and location.
We were 4 strong and there was plenty of space. Jamie didn't talk much about the rooftop when we did the tour but do your self a favor and have your after beach beers up there with some tunes.
Location wise, you can probably get to the beach in like 15 seconds if you run. Loads of good restaurants in the area and if you have wheels then it's super easy to get out or Porto Cristo to some of the other spots near by.
We had an issue where the power went out however Jamie and his son were over within 15 minutes of our whatsapp message and were able to resolve the issue as quickly as possible.
Great spot, hope to return!
