We stayed for 3 nights at the Dovecote and it's a wonderful place to spend time. The style has the right mix between traditional and modern, while inside you'll find all the amenities you'd need. The surrounding garden offers a beautiful background. The swimming pool that you can use is the icing on the cake.
Alexandros has been a friendly host, giving plenty of suggestions on activities to do on Andros and making sure your stay is as pleasant as can be.
