We are a young couple (23 yr) that stayed a few nights in Oia and then a couple nights at Nikolina's place in Firostefani. This place is clean, beautiful interior, easy to get to from Fira bus terminal and perfectly located between Fira and Imerovigli - both easy to walk to within 10 mins. Nikolina's local knowledge was also great - helping us find reliable quad bikes and the nice local places to eat, drink and watch sunset.
Thanks!
