I haven't been to Diana herself, but I lived opposite and the reviews were quite decent for 3*. The place itself is very nice and I like to relax there. Now the pandemic does not give and for the second year I suffer literally without this sea and beaches.
Nice hotel. Waiters fire! They form the agenda of all the events held. They are poorly fed. There is a nice pool. It's five minutes to the sea. The place itself is quiet. Except for a number of events held at the hotel or bars. Then yes, the rumble is worth it. But we must give them their due, after 12 at night, silence comes.
