We stayed at Nuit en Ville as a family of three adults over the Easter break. We absolutely loved our stay.
The flat has all comforts of modern living (e.g., walk-in powerful shower, dishwasher, coffee machine, open plan kitchen/dinner, comfy beds). It is a very pleasant, cozy, full of character converted flat. We stayed at the top flat which has a living area downstairs and two bedrooms upstairs. The flat is full of light and well ventilated, but not overlooked. It has a small balcony out of the living area. The kitchen is well equipped with modern stove, oven, dishwasher, tall fridge and a set of utensils. Perfect!
The check-in and check-out worked well, according to instructions received beforehand. The owner was really friendly and helpful. We met him a couple of times, and he provided quick replies to any questions we posed by email during our stay.
We would definitely recommend Nuit en Ville for those looking for a self-catering flat in Lille!
