If you're honeymooners who want to get that "We are in Santorini" I would not recommend it. Nothing in this place induces "romantic" feelings.
If you are budget conscious and just need a place to sleep, shower, and don't mind being hot and sticky due to no AC then this is the place for you.
The place is moderately clean, with old, dinge beddings and towels. No spot to just chill. No comfortable chairs or sofa.
However, it's only about a 15-20 minute walk to Oia which is where the iconic ocean, blue and white domes, shops, and restaurants are locatied.
If I were to do it again, I would not stay at Lena's Winehouse.
