This is a beautiful hotel with many great modern amenities, you get a tv, wifi, air conditioning, even a kettle and coffee right in your room with a lockbox included. There is a beautiful patio space that is comfortable and looks stylish, not to mention a breakfast area by the reception you can sit indoors if not busy. There is also a gorgeous pool with loungers available. Although things like breakfast and laundry are at an extra cost. And host is super responsive.
It is about 20min walk to Fira to catch the Local bus, where you pass by a great local supermarket that gave things like bottled water at a great price! Although can be a bit creepy if you are walking alone at night because it is dark, but Santorini is relatively safe.
Would absolutely recommend staying here as this is a great cost as well!
