The location is perfect. The metro is right down the building. You can even walk to Louvre.
Only two things need to be improved. The first is the hot water. We ran out of hot water after three people took the shower (averagely each one spent 10 minutes). The second issue is there’s only one key. Since traveling pals, especially over five, cannot always had the same plan, it’s a little bit inconvenient (my friends were locked outside for half hour at night because they failed to wake up other sleeping pals)
