Nikolina's place is a perfect compromise with cost. Little space crunch, 15-20 mins walks away from central Fira bus stop.
Definitely nearby a lot of affordable restaurants and cafes. During our whole stay we didn't see Nikolina and Renos (might be due to some emergency).
No drinking water and common kitchen was available.
Communication was very easy and instant through chats and email.
Overall, nice place with few compromises.
