We have been staying at Hotel Duo for about 20 years, every time we come to Paris. The staff is great. We've seen how the staff has improved over the years, and they're just the nicest people. Any issue that arose they addressed, or were able to offer a free breakfast for said inconvenience. A few years back an entrance for Hotel De Ville metro stop was opened just right outside the door--and it feels like your own private metro entrance. Location is great, right in the Marais and close to some of our fav shops. We are excited for their refurb coming next year, and hope that we will still be able to afford the hotel. Thanks, Hotel Duo, for another nice stay!
