It was really nice. Christos replies very quickly and answered any questions we had and was very accommodating with check in/out times. The apartment was clean and comfortable. It’s very easy to get to from the port, although involves a little up hill walk and stairs (so does everything on Serifos). The view from thee apartment is beautiful. Super close to one of the many beaches on the island. AC works great for those super hot days where you dont want the windows open.
