There is very little to say about our four days staying at this hotel: it was quite simply totally excellent in every possible respect.
Where we thought that this hotel wins is the frankly unbelievable location, the staff, the amenities, the access (be warned: some other hotels are on *extremely* steep stairs and paths) and the room quality.
We very much enjoyed the breakfasts and found that the property was very well maintained, clean and tidy and everything worked. Our room was surprisingly large and we had great service throughout our stay.
BIG pluses (we thought): the hotel is on the path to both Oia (LONG cliff top walk on rough paths at times) and in the other direction Fira (about 40 mins down hill on well maintained paths). We thought Imorvigli was an ideal location to see the whole island - and is the highest point with truly stunning views. The town is also very nice and has a plethora of excellent restaurants all within an easy walk.
Would we go back? Yes; very probably. While there must be literally dozens of other hotels and studios, on reflection we would find it immensely hard to beat staying at this hotel, if only for the views and access. Thank you!
