The location is perfect! Simple but very clean accomodation and has everything you need for exploring the Old Town. You can hear nice Greek music in the evening because taverna is just next door. The bus station is walkable distance. I did not use it as i was eating out but there is a small kitchenette in the flat if you want to cook something or enjoy a cup of tea/coffe. Good value for money. And the host is very nice and friendly.
Small suggestion: bring your ear plugs if you are super sensitive to noise. It can be a little bit noisy. With my ear plugs i was sleeping like a baby :)
Overall, if you are not looking for anything luxurious but a good bed in very clean flat with all the amenities you need, this place is for you. Perfect for staying there if you want to explore the Old Town and beautiful Harbour with lot of bars and restaurants.
