The Appartement is nice, modern style - but it has a lot of negative aspects.
1) indoor Jaquzzi- since it is only 1 room, you feel like you are sleeping in a swimming pool due to the strong smell of the chlorine water.
2) only 2 windows (1 normal - 1 tiny“ window, located up the pedestrian Zone) which you can open.
3) a lot of noise - it is directly on the pedestrian zone - through the air vents you can hear word by word what people are saying if they walk by. No chance to prevent this noise.
4) shared Terrasse - the view of the Terrasse/balcony is amazing, but it is shared with another Appartment without any privacy. So you are sitting side by side with other people. This is not what you are looking for if you are on a quite holiday trip.
5) electricity - I had one night and full day no electricity (the lady told me this happens often - not their fault). When the electricity is gone, an energy lamp is turning on - which you can’t turn off. My first night stopped at 4 o clock with a bright room - and no sleep. They turned it of for the next days, what was great.
6) water - there was over 24h no water in the full Appartement (again - not their fault!?)
7) one Hugh window with faces towards the sea - it is mirrored (people shouldn’t see in) - but if your neighbours are on the terrace - it feels very uncomfortable.
8) check out - nobody came for over 25minutes.
I stayed there 6 days/5 nights - Appartement got cleaned once - same for towels.
The host (agency agent) Irene was super nice and supportive, helped a lot with recommendations.
But the Appartment is not worth the money, you find better places in Santorini.
