We used Hotel Elilly for a workshop with our partners. The hotel and the area is quiet and suitable for workshopping and concentration. The hotel was not prepared for our workshop, when I arrived from abroad, despite intensive communication and instructions, but caught up and everything was OK in time. My advice would be to arrive early in advance of your meeting. The service is good, but again a bit slow (e.g. business service). The food could be better - some of our guests and myself got stomach trouble, probably from the food. Be early for breakfast, or you will meet an empty buffet (they are slow in refilling). My room was spacious, clean, quiet. The pool is heated - nice, but waste of energy. The staff is very nice, smiling, accommodating - 5*. In the lounge, they do an Ethiopian coffee ceremony every day - recommendable. The wifi in the room was fine, but some places (e.g. workshop area) hardly covered.
Conclusion: Very good value for money with small weaknesses. I would go there again.
