You will not find many reviews for this place as I think this is only the second year First Choice have done this hotel. Not seen it myself but as regular visitor to Halkidiki , recognize new hotels etc in the brochure or on the web. I have seen a few discussions about it on tripadvisor under the halikdiki forum but you may have to search through past posts. Also there may have been a few discussions about it on Halkidiki.com.
Im sure you will have a great time in Halkidiki anyway, we always do!
Make sure you visit Hanioti (where we stay) and Pefkohori also while you are there (neighbouring villages).

We have booked Ammos studios for two weeks in may.Can anybody tell me if the hill is very steep.Bit worried because my husband uses inhalers and would have difficulty walking back.Frances

I would recommend the day trip that crosses to the Athos peninsula and cruises the coastline to view the monastries. Our trip stopped for lunch and a swim in Ouranoupolis. The crossing can be a bit choppy
