We really enjoyed our stay at Cloe's House. It's a nice and modernly designed apartment and has just about everything you need. As others already mentioned, the apartment is not directly located at the beach, but for us it was about a 15 minute walk, which we didn't mind at all. In addition, there's lots of e-scooters that can be rented around the apartment, which can be used for the way to the beach. Close tothe apartment there were also a few opportunities for food shopping as well as a little bakery about a 7-minute walk away from the apartment.
Communication with Rosi was fine as she replied to our messages really quickly and was very helpful, sometimes there seemed to be a bit of a language barrier due to false translations though. The kitchen was fine to cook simple meals, but if you plan to cook a lot I'd advise to bring a few additional utensils especially knives. We didn't really mind that since Mondello offers lots of good and oftentimes rather cheap options for eating out.
All in all, our stay at Cloe's House was a really pleasant one and we'd definitely come back to this apartment.
