Hi Julia i stayed at the Mersoy in Sept 2005 we had a great time. The rooms are basic but clean, the pool was very clean too.
We only stayed bed and breakfast as we like to try different places. The guys who work in the restaurant at the front entrance are fabulous Muzzy and Fonzy (still there last Sept) they make you very welcome and soon became good friends who we still see when we on holiday
The Mersoy exclusive has a lovely indoor pool and gym, turkish baths etc which you can use (pool is free) but wonderful for a Turkish Bath and massage
We stay at the Elif now only because i like where it is situated. Hope this info helps
