Modern, up-to-date apartmanets, great lay out, lots of light anf life, convieniently located, great dining places in the same block, one small market in the same mall area and bigger grocery store near by, fantastic service by every single staffer, Rebeca is a sweetheart, and Kellyana is on top of things. I go to CR every year once year and always go to a different place, but from now own, Apartamentos Cityzen will be my Tico-Home.
