The house is located 5-7 minutes taxi ride from Fira. We (8 adults and 1 child) unfortunately didn't meet Sofia as she wasn't keeping well. But that did not stop her from arranging tours for us. The house is beautiful and with three bedrooms and 2 toilets. However, the smaller toilets is too small. The house is sparkling clean and Miranda kept it so tidy for us. It has a beautiful view of Aegean Sea and the coastline. It was our bad luck that the weather wasn't amazing. Thank you Sofia for hosting us and all the courtesies that you extended to us during our stay there.
Tip for other travellers: Travelling from Sofia's home to the Fira city centre is very easy and takes about 5-7 minutes by cab. The host had booked 2 cars for us. But somehow we felt these drivers were charging us much above the market rate. For this small journey, the drivers charged us €20 per car. We paid a total of €40. So we decided to check the local taxi and the two local taxis that we took later cost us a total of only €16.
So to book a cab from Sofia's home to Fira call the local taxi station at +3022860 22555, 22860 23951. And tell them you are in front of 'Pension Anna Vazeou', which is only 20 seconds walk from Sofia's home. They will charge only €8. From Fira, you'll get lovely buses to every destination you many want to visit in Santorini. And tickets cost only about €2.
