As far as I know only the MLS will let you filter search results. I would recommend you find a Realtor to help you find what you are looking for since they have access to the MLS. There are probably a few apartments in Boca Raton that have eat in kitchens or breakfast nooks, it's just a matter of knowing exactly what you are looking for, such as how many bedrooms, any pets, what's your budget, what specific area in Boca, etc?
