We didn't expect a palace, but we thought we were getting a bargain on a plain but decent hotel in Piraeus, the port area of Athens, not a chic neighborhood. The picture of the hotel on Expedia is photoshopped. The picture of the room shows something bearing no resemblance to ours. The door was warped and hard to lock. I could have easily kicked it to pieces. The bathroom door was rotting and had been repaired with a Frankenstein pieces of plywood. There is no blue sky on either side of the building. There was hot water, but the shower was tiny and would let water out on the floor, the bathroom was dingy, the WiFi didn't work. It took a full day before the morning desk attendant (who was very nice) rebooted it. I get it most people now use cell phones but T-Mobile throttled me when I exceeded 5gb for the month so wifi was important to me. And it was advertised. They also advertised a buffet you had to pay for but that was cancelled in covid 4 years ago. As I said one person at the desk was great, one was good, but there were a couple of surly ones too. They didn't ask for a passport one time and handed me the key leading me to think that anyone could get into our room potentially by asking at the right time.
In short, if you're selling a dump for 74 euros a night, be up front about it. I found lovely apartments in great neighborhoods for 100, but we thought this would be convenient. I would recommend against the delfini until they change their business practices.
