this intimate little hotel right off the sand is a great spot if you're a budget traveler looking to book a simple room that's walking distance to some of the most popular beaches on the island. the proprietors (Nicos, George, Dimitris & Marsoula) are all quite nice, as is the hotel waitress, Andzelika. Nicos' English seems to be the strongest, so he's the go-to guy for more complex questions in that language.
George was late to pick me up from the airport, though I didn't mind as the wait wasn't long. I appreciated that pick-up from the airport was complimentary (I stayed 4 nights). It cost 20 euro for George to drive me to the New Port for my departure; Nicos said that was generally what taxis would charge as well.
Platis Gialos and Paraga beaches are both short walks away on foot. Heading to Paraga, you'll walk a few minutes up a small hill, on pavement alongside traffic. Heading to Platis Gialos, you'll walk a dirt path on a small incline next to the sea. To access Paradise/Super Paradise, you'll need a vehicle.
I enjoyed the hotel restaurant's pork gyros and french fries, and while the Greek coffee wasn't my personal favorite, I'm glad I tried it. Prices on food/drink are moderate for that part of the island; though at check-out 1 euro was added to the advertised cost of each dish, so they need to update the menu prices on their board.
Nikolas Tavern next door does yummy, straightforward Greek and Italian food at similar prices. For a ritzier, slightly more expensive vibe, head to Platis Gialos. The cheapest local food options are at Paraga (Castello Cafeteria, Cafe/Bar Paraga).
A single sun lounger on their stretch of beach costs 9 euro, which is also moderate compared to the cost of loungers at the surrounding beaches. The hotel is right next to an open-air bar called Pinky Beach; one night they hosted a wedding celebration and music played until pretty late. I wasn't bothered by this, but lighter sleepers should be aware of this during high season. Overall, Agia Anna is definitely quieter compared to places closer to the local day party/nightlife spots (SantAnna, Scorpios, Kalua, etc).
The only negative for me was the bed in my room (#10) not being very comfortable, though it seems harder mattresses are just part of the deal when you do Greece on the cheap. I used pillows from the couch-type lounger in my room to pad it, so I made due.
Overall I enjoyed my stay at Agia Anna Studios. They represent what they have to offer on Airbnb pretty accurately :)
