This location is incredible! It was perfect for our last few days of shopping in Paris. Yes you can hear the subway but I am a deep sleeper and the bed was comfortable it didn't bother us. Only tricky part was the initial check in as we didn't have internet outside of wifi while traveling so email as the main point of contact was tricky and the mobile phone wasn't being answered so just make sure you get in touch a few days before check in via email. But highly recommend and would definitely look to stay here again - ground floor apartments are such a blessing in Paris and hard to find! Thank you for having us Benoit. :)
