Alex's place is in a great location - really close to the great bars and restaurants of Firostefani, and a leisurely 10 min walk from Imerovigli and 15 from Fira. There's a terrace on either side of the flat so you have views to both sides of the island. The road outside is a bit busy but there are shutters on all the windows to help block out some of the noise.
The complimentary shuttle service when we arrived was really helpful and took away some of the stress at the busy port.
Communication with Alex was quick and easy, with beautiful English. He was very welcoming and a great host. He had lots of advice on things to do and could help with tour bookings.
Would definitely recommend.
