Stefania was a really gracious host, nice person, and very accommodating. she helped us organize a transfer from the port and even performed as a souvlaki grill master one afternoon (which everyone raved about). The house is a very quirky cave house, perfect for accommodating a large wedding group.
The location is pretty ideal. It's a 7-10 minute taxi from the fun and games in Fira, however you're located on the periphery of a quaint local town in Santorini. There are plenty of good restaurants and supermarkets nearby. Having a pool was major plus others not staying with us struggled to find accommodations with anything larger than a plunge pool.
