Huge space, clean and functional. Good communication. It's a rental business with many properties. On a big road, bit brutal, so it's a walk to get to restaurants etc but we picked it to be close to the Museum of Islamic Art. And it's easy to get a 5-min cab to nice cafes around Thisseio and the flea market. We came by metro from Piraeus but there was a pickpocket gang on the train so be very aware. Other friends have had same experience. The accommodation can arrange a taxi for you instead.
