Spacious apartment with large partly-enclosed veranda, I spent a lot of time relaxing outside. Good wifi, well-equipped kitchen, everything you need for a longer stay. Good location close to 2 metro lines, and plenty of shops, supermarkets, bakeries and coffee just across the rail line. About 800m walk from Liossion bus station with airport bus and intercity services, and not too far from central train station. I didn't feel unsafe, even walking at night in the area. Thelxi responded fast when I had questions or a problem with the hot water and her local "assistant", although he has little English, was very helpful.
Just a heads-up for non-smokers (and this is my fault for not checking) the apartment has been used by heavy smokers for many years so it does smell quite strongly of cigarettes. In fact there was a dirty ashtray on the coffee table when I arrived. If you are sensitive like me to cigarette smells, this may not be for you.
