We stayed in the Artemis 6 Room, it was exactly like the photos. The room was spacious, clean, had a small balcony (no view, but it wasnt necessary), it was a quietish area, but what impressed us the most was the little details, the noise plugs, eye-mask, complimentary lemonade, the hand written welcome note etc. This hotel is owned by a company that specializes in small boutique apartments across Greece and it shows, they seem to really know their craft.
Add to that some super friendly and professional staff (special thanks to the cleaning lady and the receptionist who were both equally lovely).
The location is safe and central perfect for exploring the centre by day / night. Would happily stay again. Recommended.
