We stayed here as a group of 4. It was a little tight for 4 people, but the location was really great and convenient to everything that you might need. It was also a great spot for all of the tour pick ups if you decide to do a tour of the island. Highly recommend doing a catamaran tour !
Fira is the place to stay if you are looking to experience the night life and be close to all of the shops.
Fotini was a very responsive and communicative host. She helped organize taxi transfers for us and gave us a lot of recommendations about what to do while in Santorini.
