We had a great stay at Anna's. It's a nice and quiet 2 bedroom apartment with a quiet shaded balcony on one side and another long balcony on the other which faces a park and the street and has a view of the mountains. It's a close and flat walk to downtown, maybe 5-10mins. It's close to a shopping area and plenty of restaurants, and there's a supermarket just a few doors down.
There's a decent kitchen if you choose to do groceries and cook, but there are also a lot of good food choices nearby that stay open late and are reasonably priced. There was also plenty of hot water for showers and a little washing machine.
You could walk to/from the ferry port, but Anna also provided us with transportation, which was convenient because we had baggage. It's also a short walk to a nearby beach. We also walked from the apartment up to Chrysostomos Monastery which has great views of the city and the water. It takes maybe 30mins to get up there and a little less to get back to the apartment, so I recommend doing that if you're able to.
