we visited the sunvalley apartment in May this year as we had contacted the owner who was very very helpfull, we never saw inside the apartment as we knew after visiting that it was not for us... the reason for this is we like a smaller complex, and did not need to be that close to the beach.....
the apartment is in a great position for the beach/restaurants, the dolmus runs a 5 minute walk away and there is a small shop 5 minutes walk away that sells all your needs, so i would say very convenient if you want to be close to the beach area..
not sure where mirage apartments are..
