We stayed at Hotel Sofia on our vacation to Greece. We loved the location. It was close to a lot of restaurants and shops and only a 10 minute walk from Fira. The hotel does not have a completely unubstructed view from the balcony, but there is an overlook just 60 meters away so you can watch the sunset. For 50 euros, it was a good price for Santorini.
Having the transfers included in the price was nice too, but be careful if a cab is arranged for you to leave Santorini from the port or the airport. Our taxi driver tried to scam us out of 15 euros. He kept telling us we needed to pay him, but we knew our transfers were included. He even tried to "call" Sofia, but he didn't even dial a number.
