Nicole’s place was great for our group of four. It looks even better than the photos and the location is hard to beat (though be warned you will probably be woken up on the weekend by services at the church just steps away, it’s quite pretty though). You’re in the heart of town with easy access to shops, restaurants, and bars. Would still recommend renting a car or scoots to get to the nicer beaches as cabs are limited on Mykonos and the bus can take a while.
The air conditioner upstairs wasn’t working for most of our stay but Nicole was able to get someone in the replace the unit when it couldn’t be fixed. Having a private roof is a great boon, but best for nighttime as there’s no shade. It is a small space, especially the bathrooms, but utilized well.
Finally, and this is more for Airbnb, music was banned in Mykonos the week we were there and we tried to get refunded but could not. I would watch the news carefully to see how Covid restrictions may affect your trip. While we had a good time, much of what people come to Mykonos for is the nightlife scene which was severely constrained during our stay.
