You can no doubt ask your Tour Operator to request specific rooms. Most 1 bedroomed appartments will have your main bedroom and the living area as seperate rooms, so no matter what appartment you are allocated you are unlikley to be sleeping in the same rooms.

You could also email/telephone your hotel and request a specific room, you will find most hotels very accomodating if there booking sheet is not too full.

We stayed in an attic room at Club Kocer last year. They are quite small, but do have a seperate bedroom so you won't be all in the one room. However, to get to the toilet and bathroom you had to go through the bedroom. It wasn't a problem for us as there was only me and my wife, but may not be so good for you. I assume all attic rooms will have this lay out.

please be aware the attic rooms are not all the same. our first stay at kocer we had attic room for myself hubby and teen daughter ,this was quite large ,only problem was the stairs .what a killer. our neighbourghs next door asked to be moved as theres was tiny and the bedroom just fitted a double bed and the shower room was so small you had to duck to enter, the next visit we had 3 rooms,ours was not attic but my daughters was ,toilet was in bedroom and the room was small. the third room was even smaller,,it seems that if theres only 2 of you you may be given the smallest rooms ,xxx jan

we stayed in a "normal" room previously and you had to go through bedroom for the bathroom in there so sounds like nearly all rooms have that layout

going again in 8 weeks - can't wait!
