We stayed here for ~1 week with a family and kids and really enjoyed this hotel. It is family run hotel and they really make you feel at home - trying to solve all the issues that may arise.
Location: close to city center (5 min bike/15 min walk) and just one block from the beach line - so you do not need bike to go beach.
Beach: They have arrangements with nearby beaches - so you can rent tent from the hotel and do not spend any extra time on booking beach yourself
Breakfast: cute area and they prepare literally everything you want, just ask. Good thing that breakfast is served till 12 or so - very convenient for those who wake up late
Bikes: you can rent nice branded city bike, trycicle and kids bike directly from hotel - very convenient
Rooms: small (which is ok for italy/forte) but clean and nice
Very nice chillout zone to have a drink or two at the entrance
The only issue we had - when in the room you can hear noise from the corridor when someone walks or shouts. Other than that - perfect experience. One of the best places to stay in FdM for short period of time. If we come to FdM for short stay - will definitely choose Olimpia.
Tip: Do ask staff if you need anything - they are super helpful + they know everything around
