I enjoyed my stay at Katerina's place. It offers good value in a great, quiet location - but still close to all the action in Fira - just 5 mins walking to the centre.
The place offers clean, comfortable accommodation with basic utensils and good AC. There's wifi access, but I used mobile internet - there's good 4G signal at this location.
I used Katerina's transfer service - this made everything simple - especially as finding the property the first time is tricky until you get your bearings.
Overall a positive experience - only two suggestions for improvements - the place gets very bright early in the morning - it could do with some blinds to block the light. Also, the communication with the host was sometimes slow - had to chase a few times to be sure everything was OK.
