We stay at Rosetta about 1 month during our summer internship. The location is very beutifull and very calm. In 2 minutes you can find beach with spectacular sunsets and area for rest. You can get to the city center of Lalysson very eaisly along the road or along the beach ( but be carefull its stone not sandy) , the walk takes about 20 min. Room was exactly the same like in the picture. One thing that you have to be aware -> in the objects are many cats and they can very easily enter your room without any reason. So be aware that you will have to sleep with close door/window and working air conditiong for the whole night. At the begining that was a bit problematic for us but we used to :)
Greetings for you , and we wish all the best .
Izabela and Julia.
