We were on a family trip and rented two apartments in the same street, just 1 block apart. I have lived in the marai for 3 years and have to say the area around châtelet has really cleaned itself up, so dont hesitate to book an apartment there! As for the specifics of the apartment: it gets very hot beneath the roof so for people who might suffer from heat in simmer it's not ideal. It was clean but def not 5 star cosy clean and equiped with the basics. Personally I prefer airbnb apartments that feel lived in rather than those that are rented out back to back to tourists.
