Everything about this place was excellent from start to finish! It's exactly as shown, and communication with owner and caretaker was clear, accurate, and timely.
We had our kids with us for 1 of 7 nights in early July 2021, and I slept on the futon in the living room. It was actually very comfortable! The apartment is likely best for couples or adults with kids (rather than 4 adults).
Views are amazing, and we swam at the sea across the road every day. We had many lovely runs/walks down the promenade. It's very easy to get around on the bus or trams, although we actually enjoyed the walk to the old town for dinner (about 4 km or a 50 minute walk).
The place is fully equipped; we enjoyed using their beach chairs and umbrellas. The air conditioning works well which made for good sleeps at night.
Parking was a concern before we arrived, but it worked out totally fine with street parking. We generally took our car to explore during the day, and were able to find street parking on our return. It's not expensive at all (unless you try to leave your car for a full weekday in which case the price goes up quite a bit), and overnight (8pm until around 9am) is also very cheap. You can also use the PaybyPhone app to renew your parking, so you don't even need to go back outside to pay (you'll need to cancel your existing parking and enter a new one, as the Extend feature doesn't seem to work). So we didn't end up using a nearby lot, rather we parked on the street.
Would definitely recommend this place if you are visiting Nice.
