The location is fantastic. You can walk to multiple metro stations on different lines, but our favourite was the bastille as it is a simple straight walk away with multiple lines intersecting. The vicinity (like just across the roads) has supermarkets to load up on supplies. Heaps of good restaurants, cafe, bakery in the surroundings. Very convenient.
The apartment was great, lots of space in the living area, great for our family with 2 kids. Our boys are able to even have their piano practice on the grand piano. ;p We have also used the kitchen quite a bit, you have everything you need to cook a simple meal.
Overall we enjoyed our stay in Paris at Hugues Apartment and would recommend it again if we were to head back to Paris.
