I was visiting the hotel with my sister her husband and their children and I must say it was fantastic. Its really worth it.
BUT:
Be prepared for some surprises:
1; the beach is not so near as it says on sites BUT you can use a free shuttle there and back any time from 9 AM what was fantastic after all day on the sun. And the children enjoyed it very much cause they liked the horses. ( don't forget to thank the horse for the ride with a bit of sugar ;) )
2; well the buffet selection is hmm a bit poor but be sure not to eat or try to eat a bit from each dish it afterwords you will and like me with pasta and bread :D
3; the chambermaids will prepare some surprises almost each night of your stay i wont share the photos with it wouldn't be any surprise then ;)

Well there is one thing i didnt like so much: Can you speak French? They "love you". You dont? Well the staff don't care so much about you as about French speaking guests.
BUUUUT there are some exceptions and I must say that they made it good :)

Isis spa has a 4 start rating (joke).... My opinion is that it deserves at the most a 2.5 star rating. The rooms are just acceptable and the food is standard. It is a tourist class hotel with no frills.

From the Isis Hotel remain, essentially, two memories: a great pool and the bad service provided by staff of the restaurant and bars.

The room´s dimension is regular, but our balcony´s view was to the rear of the SPA and the door of the kitchen (we always knew what would be the lunch and dinner) - the hotel Isis announces that "all rooms have a view to the pool or for our inner gardens".

The beach is about 500 meters and there are carriages out regularly going to the beach. The beach itself is only for hotel guests and has a bar that serves (only) water and juices between 10:00 a.m. and 17:00 p.m.

The food is divided between local food and food towards the French taste and is, is general, poorly made and lacking variety. We get a feeling of an unsanitary service (for example, the wine is served in pitchers that are not washed between the different consumers).

The all-inclusive service includes merely water, juice, beer and wine, and only in the period between 10:00 a.m. and 22:00 p.m.

The employees of the reception and the animators were friendly but the ones in the restaurant and the bars were, in general, very rude and unavailable.

The pool is great, with water at a pleasant temperature and usually with enough chairs to accommodate everyone.

If you don´t speak French, don´t go to this hotel because nobody will make an effort to understand you.

I think the hotel is overrated and I don´t intend to return.
