Jinping's place worked great for us. It's brand new and sparkling clean, offers eye-popping views and is conveniently located 3mins from Platis Gialos.
My fam and I decided last minute to extend our visit to Sifnos and Jinping took our booking and was ready for us to check-in almost immediately, same day, which was very helpful. She was also super friendly.
As it's a brand new place it's missing a few things that I think will make it more comfortable in the heat and wind, like a covering over the patio, it's a bit exposed for dining or hanging out.
The interior lacks a bit of the traditional Sifnian character that some people may be looking for, and the beds are a bit hard (I imagine because they are brand new). The common area inside is a bit small so I'd recommend it for a small family or a couple, or as an affordable crash pad for a small group of friends. It's clean, has everything you need amenities wise, the AC works great, for a brand new listing it's a great start! Oh and the adorable kittens are a bonus! Thanks Jinping!
