Only the ground floor rooms at the Ecesaray have just walk in showers, all rooms on the higher floors have baths with showers over.
Unique is a lovely hotel, accommodation very comfortable, but dye to the location, at some times of the year, the sun, if it is out,!, is limited. The public areas in both the Yacht Classic and Ecesaray do not suffer from this.
Only the Ecesaray has rooms that all have seaview, so maybe a consideration when booking other hotels and check your room does have a seaview.
