We stayed in studio no.3, so can only really review that one.
Pros:
very quiet location
Cleaned every day
New sheets and towels every other day
Lovely friendly host and cleaner
Decent size balcony
30 seconds walk to the beach
The shower is lovely and powerful.

Cons:
it was advertised as having a washing machine-it did not
Bulb out in one of the lamps
It’s quite dark
It’s very compact.
The driveway is easy to miss and very narrow.
The wifi is shockingly bad. We ended up using data and turning wifi off.
We had a lovely week away, and very much love Stegna. For anyone who wants to visit Stegna, make sure you have a car as it’s off the beaten track which is why we love it.
The studio was very quaint and compact. Christos left us a nice carton of juice as a welcome gift. The fridge is decent and there’s a small freezer area for ice etc.
If you stay in studio 3, take your own travel washing line. We took one and were so glad we did!
The balcony gets red hot in the morning but was very nice for breakfast.
Overall we enjoyed our stay!
Oh, and watch out for the shower curtain that attacks you whilst you’re in there!
