One of my favourite spot in Rome, especially in May and June, is the swimming area of the Rome Cavalieri. This five stars hotel is part of the Waldorf Astoria Group. I love it because they have a great view and they offer two separates pools: one for children and one for adults. If you go there, during the week (Monday through Friday), you can lie on the sun for 45 euros. When I'm there for lunch, I always ask for the classic club sandwich but you can have burgers with french fries. For drinks I suggest a strawberry Daiquiri or a Mediterranean breeze based on vodka, ananas, lime, banana and granatina. Enjoy!
