1/ Location: Great location, walking distance to old city, port, beach, virtually everything. No need for rental
2/ Beach: surprisingly very clean, calm. however avoid booking during july-august, it gets very crowded and solicited. beach is about few yards from hotel, need to cross a street but no biggy.
3/ Restaurent: very very average. not great selection of food. staff at the restaurent is not knowledgeable, sometime rude, kept asking when we're leaving and had hard time keeping us on the same table, very confusing and probably not too experienced. I suggest Delphin replaces 'maitre d'hotel' or send him on a training.
4/ Room: outdated, but clean, AC worked fine. Hallways were dim and hard to navigate during the evening, they have those motion detectors to turn on light that hardly worked, thus you need a flashlight (i used my iphone light) to get to your room
5/ Entertainment: boring, 80's style. good for Russian tourists and the likes, nothing close to US Standards.
Overall, it's a decent hotel if you want to stay 1-2 nights say for business or quick visit of the city of Monastir which has very few historical sites. if you're looking for a longer stay inside a resort, find something in Skanes which has plenty of 4+ stars resorts.
Hope this helped !
