Wife, me and friends had 4 different rooms one year in 2 different blocks, didn't notice any room size difference and all had a/cond, tv, fridge, breakfast in the price. Only 1 room in the far block on the top had no balcony.
Didn't stay there last season - prices were rising, and no compromise to us for long term customers and bringing them new customers, sad really but I would have expected better from them, love the place, but won't be held to ransom.
Not sure if the 'extras' are all seperatly charged or not booking DIY, I think they are if you book with tour operator ?
