10/10 would recommend a room at Anna Pension to anyone visiting Santorini.
Location: We stayed here at the end of March 2023 for 4 days. The hotel was smack dab in the middle of the island, within a 30min drive to every major attraction from oia in the north, to akrotiri in the south. We opted to rent a car to maximize our time, and highly recommend this to you as well if visiting Santorini for the first time (parking on a sidesteeet right at the airbnb). That said, right from check-in Andreas was super helpful in providing instructions for local bus routes, transportation services, and various other concierge services. The immediate walkable area of karterados is cool on its own, with marts, pharmacies, cafes, bakeries, restaurants, and bars all within 10 min by foot. I personally recommend “Home All Day Cafe” for both breakfast and nightlife.
Space: 5ish rooms on our floor, seemed to be an upstairs and downstairs with more. There is a large common area with many different comfy spots to lounge indoor and out next to a decently sized pool. The view is primarily of the east where peaking through buildings you can see church-bells and the sea in the distance. You can choose to interact with other guests here, order basic drinks/snacks, and they even serve breakfast in the mornings.
Room: Nicely furnished, small room with two twin beds pushed together to make a double. Immaculately clean, cleaning staff only come if requested, giving you privacy if you choose. There is a fridge in the room, personal balcony for 2-3 people to fit, and small hostel style bathroom. Although the shower seems simple at first glance, it stayed hot with great pressure/settings for after our intense hikes! You can hear some noise from around the city and airbnb through the walls, but you should expect this in any stay on the island of santorini unless you want an airbnb in the middle of nowhere away from civilization. It was not hot on the island in march when we stayed, but if it was there was a personal air conditioning unit above the bed area that I imagine is very effective.
Staff: Easily the best part. Even the newest staff member was able to quickly help us book tours, order laundry service, and get us what we needed day or night. Andreas runs a small tightly run operation which has the service of a full hotel, but feel of a family run bnb. They go above and beyond to help and seem to love sharing their island with foreigners. Also, their english was great and very convenient for providing help for us!
Perfect “bang-for-your-buck” option for those wishing to see a lot of island in a short time, with restful accommodations in between!
