We loved the Hippocampus for out 5 night stay. It's a well amenitied hotel with 2 beautiful pools and a 2 minute (or less) walk to the beach. It is also close to the bus stop for going to Thira/Oia. The staff (shout out to Elpida especially who clearly loves making her clients happy) is warm and very helpful. We upgraded our room to the maisonette, which is located ground level with a big porch and has 2 bedrooms (one upstairs) and a small living room. The hotel offers a nice breakfast buffet, robes, slippers, toiletries, and beach towels. The only thing we didn't appreciate was the sulphur smell that took a bit of getting used to. That being said, we would stay there again in a heartbeat and highly recommend it!
