Don't worry, if you book this you can't go wrong.
The villa: As beautiful as in the pictures. Awesome pool with gorgeous views and nicely furnished inside with all amenities as needed (no kitchen though, but a fridge). A friendly lady stopped by daily if we needed cleaning, new towels or coffee tabs. Super-comfy beds!
Great location in beautiful Pyrgos, just a few minutes walk to the main square and old town. Great places to eat nearby. You have all the charm of Santorini without the unpleasant crowds as in Thira or Oia at sunset. Join a wine tasting at Santo winery at sunset instead (3 minutes by car). We arrived without a reservation at 7pm and got a very nice table.
The host: Panagiotis provided really exceptional service. He even organized a transfer from the ferry port to our first accommodation in Imerovigli, even though we were staying in a different location. He also gave us a lot of information about things to do, but.... we stayed in the villa during the day and just enjoyed the place. Very good price quality ratio.
