The location of the apartment is fantastic with good access to public transport, and walkable to tourist attractions, shops and restaurants. Emre was very accommodating and responsive and booked me a taxi for my very early flight. Was also able to store my bag so I did not have to haul it up the stairs.
About the stairs, be aware that it is a spiral staircase with narrow steps. The apartment is on the 3rd floor (4th level) and I would not recommend for older travellers or people with large suitcases.
The apartment is very small but very clean. It would be good for a couple and a child but might be cramped for 3 adults.
