Hi Chris, 
Having spoken to a colleague, the hotel does have guests of a variety of ages visit however we would be unable to guarantee the ages of those travellers. I understand that the hotel is close to the beach, bars, restaurants and public transport if you wanted to get out and about a bit. 
Now, my colleague who looks after the Facebook page mentioned a few other destinations that you were interested in so I did a little bit of digging and found... 
Our Sun-Kissed Sardinia trip departing 1st June which currently has 17 travellers confirmed to travel, one is in their mid-30s. 
Alternatively, our sister company Travelsphere has a Sardinia & Corsica tour departing on the 5th June. Out of the 16 travellers booked - there are 4 travellers booked as single travellers and the ages of the whole group are from early-40s through to mid-80s. 
Kindest regards, 
Julia
