My husband and I very much enjoyed our stay in the Poseidon and would stay again! The location is so convenient to many walkable activities and the interior and features were just as described.
We appreciated receiving very clear check-in instructions in advance as well as the offer for concierge services (while we didn't take advantage of the concierge service as we've spent time in the area quite a few times before, it sounded very comprehensive).
Though technically a studio, the bedroom nook is separated enough to feel very cozy, and the bed and bedding were very comfy. The kitchen was well stocked with cooking utensils, pots, pans & small appliances, and dishes - everything you need and nothing you don't for casual cooking or baking. Items in the kitchen and bathroom all appeared quite clean, but the cleanliness of the overall apartment could use some attention (for example, sticky and discolored doorframes and handles on closet and entry doors).
