This apartment is centrally located and I believe would be good value for a party of 4 people, as the space is certainly big enough and the 2 bedrooms are very large. It is situated next to a lively square which has various options for breakfast or dinner and is very close to the Tourist Information office.
The check-in/check-out system is efficient. The apartment lacks any outside space which could be a drawback in summer, if you enjoy eating al fresco. Light sleepers should note that there is a bar next door which has an outside terrace virtually under the apartment which is noisy with customers until midnight and plays loud music til midnight on Saturday nights. Again, I think this could be more of an issue in summer as you would want to have the windows open although it was less of a problem out of high season.
Bathroom is basic but functional and the actual shower tray is very large.
The apartment is well stocked, for example there are beach towels, a clothes airer, a shopping bag and the kitchen is useful if you want to cook as there is a full size fridge and a halogen hob plus cutlery, glasses, cooking utensils and plates.
It was possible to find a parking space in the surrounding streets although it took some hunting. Not sure if this would be easy in July and August though.
A note about the food market in Ciutadella; which is main reason why I chose an apartment with a kitchen: the fish market is good, (although expensive) but there are only a few stalls selling fruit and vegetables, which surprised me. There are also numerous stalls selling meat and cheese products. The seafood selection in the market is very good and it is also worth investigating locally made cured meats and cheeses. There are also various supermarkets situated close to the apartment. A word about the water: various local people told me that you "should not drink the tap water in Menorca" (apparently it is polluted with nitrates) so the fridge is actually very handy for keeping chilled bottled water!
