My wife and I had a wonderful stay here. It is definitely tight in the bedroom and bathroom, but worth it in our opinion. The location in particular was what made this so amazing. It's not everyday that you get to stay inside of a medieval world heritage city. Everything you could need is within walking distance including restaurants, shops, rentals and buses.
I do not recommend taking the bus from the airport. We did so and there was barely room to breathe. Buses to other areas of the island are much less packed and accessible. They depart from the ktel station in Rhodes.
The hosts were very accommodating as well. They let us stay a bit longer since we had a late flight and set up a taxi transfer to the airport as well. Along with a golf cart to get us out of the city walls since non residents cannot enter with a vehicle. I highly recommend it.
