"It was incredibly nice here! The pool and scene is so calm and peaceful. We rented the 2 BR villa and I highly recommend. You get your own pool! The breakfast basket was intentional and artfully crafted! I do recommend having a car because the walk to Apollonia on the trails is about 45 minutes. ..."
