I stayed as a solo traveller with Mouria and I can only give the most excellent of reviews for absolutely everything.
The landlady and Monica (who kept our rooms super clean and was a perfect hostess at breakfast too) were just so nice - I felt safe, welcome and at home from the moment I checked in.
The location is superb - literally off the main street in Skiathos town. I was a little anxious about the noise but everything close by like the taverna was closed up the time i got to bed each night so no issues there.
Facilities were fab - super comfy double bed, air con, modern and clean en suite and there's a communal kitchen (with kettle! Definite perk for any fellow Brits).
Kitchen is free every morning for folks staying at the hotel - its not open to the public in the morning. Really nice and fresh - pastries, bread and honey / jam, greek yoghurt and fruit, tea and coffee, orange juice.
I wouldn't stay anywhere else! I have already spoken to my partner about going back next year.
Thank you for a wonderful stay! Sophie
