Our time at the Sweet Inn was wonderful. The location is absolutely perfect - close to restaurants and shopping and the metro. We felt very safe there. A 10 minute walk to Notre Dame and 15 minute walk to the Louvre. We had a couple of tiny issues, but nothing that was not solved quickly. The app and the chat function worked great - and communication through the chat was answered quickly. The apartment was very clean and the beds are comfortable. The neighborhood is 'hopping' until about midnight, even during weekdays, which did not bother us too much. We stayed up and enjoyed it - but it may be bothersome to those who like to retire early. We highly recommend staying at the Sweet Inn on your next trip to Paris.
