The good: The location is indeed very convenient. The flat is small, but then that is normal for a place in a Parisian building, and it is quite clear from the photos that there is not much space. The kitchen is well equipped - there was salt, pepper and olive oil, and an abundance of coffee pods for the Nespresso machine. The bathroom is very clean and modern. Plenty of towels and Molton Brown soap, shampoo and conditioner. The mattresses are very comfortable. Each bedroom and the living area have air conditioning machines as well as fans.
The not so good: I was informed shortly after booking (and paying in full) that the lift had broken down. Climbing 6 floors after a long day of sight seeing was not what I expected or wanted. The lift was repaired on Monday, but when I took it it got stuck, which freaked me out. It finally moved again and I got to the top floor - but did NOT use it after that. I was also not informed that workmen were due in at 8.00 every day to paint the stairwell. The Merveil team should really be better informed and advise their clients before they book not after.
