The location of the apartment is great. You can walk to all tourist points. We didn' t meet Mariella, but Doli took care of our needs and even help us solve some issues. Its a large apartment, we were 3 and didn't feel crowded. keep in mind that the apartment is on the 2nd floor but for europe that means 3rd floor..and the stairs are very narrow. if you have heavy luugage and not strong enough that will be an issue. The apartment was clean, but needs some maintenance.....some appliances like kettle, toaster were old....and also the sheets and towels.
