Communication before arrival was excellent. My DROSSOS pick up was notable(Theodore). However, two of my friends were sick, arrived later, which caused challenges.
The host, Yanni, walked me to the rental. He was talking on his cell phone (by ear piece) most of the walk. He showed me how things worked, contact number, internet password, encouraged questions, and offered many brochures.
One IMPORTANT factor he failed to mention: there is only ONE key to the rental (unlike hotel keys for each guest). It's usually not a big deal but the key was necessary for all power usage in the room. The issue: once you locked the door from the outside, anyone left inside was locked in, causing a major problem for us.
I had two vomiting/diarrhea friends back in Mykonos who could not travel with me, arrived late, and had to sleep. So, I locked the door solely thinking about safety. I was not aware they’d be locked in the room without power. They woke up, had no power, and were locked in. Yanni was eventually notified and came.

After he arrived, friend noted the internet was not working (Thursday). He gave another internet code for a property close by and said he’d come Fri to fix the problem. But it was NOT working by Fri evening.

My friend also noted we had no sheets/blankets for the futon. He said he would bring them Friday but we never received another set.

Friday evening, we called Yanni to have a calm discussion about services. However, he became defensive when I mentioned a couple disappointments. He made excuses, tried blaming us because we did not arrive together, and continued his verbal aggression/negative attitude.
I stated the Jacuzzi button was jammed and was concerned about wasting energy. He remarked how we must have broken it. We tried asking if a later checkout was possible because we had a morning tour. He pointed out checkout time was "10", as he was already permitting us to checkout at 11. I showed him my booking confirmation which clearly stated checkout was already 11 . This triggered an angry response from him. At this point, I asked him to leave. He complied but continued making rude remarks, along with a phony apology.

Regular check out time was no problem if told it was impossible b/c new guests arriving. I know how important it is for hosts to have a rental at the scheduled time. However, the way he RUDELY said it, was unacceptable in my pt of view. He eventually offered us later check out WHILE WE WERE ACTUALLY CHECKING OUT. This was AFTER we set up our own ride/tour.

I did NOT want to leave any negative feedback because rental was BEAUTIFUL WITH PRICELESS VIEWS. I expected 5* host in a 5* rental.
Customer service is very important. Challenges are likely to happen throughout travels, and the host must be trained to handle them.

Rating on property itself 5 *, rating on host rep 2*
