We loved Olga's place. It is in the old town of Andros and is quaint and gorgeous. The location is fantastic with 2 beaches within walking distance. A car is necessary in Andros and the nearest place to park is by the cinema which is about a 5 minute walk because the town is pedestrianized. This is very easy to do and was no issue at all. Also the car park is free.
We would definitely stay here again.
You need to be self sufficient in terms of working out where to go, where the supermarket is, and what to do because there is no guidebook or information provided in the house. However, this is not too hard to figure out, but you should not be expecting recommendations unless this changes.
