We stayed for 3 nights in Sep 2017 (2 people) and had a great time. The communication with Yue was direct and easy. She gave us a very detailed and helpful intro via mail 24h before we arrived and told us everything we needed to know - including recommendations on cafés & stores near-by.
The apartment was beautiful and clean. The WC is very small, but the rest of the place is perfect for two people. There is enough water for two people, but it only refills around 11am, so we only had cold whater on the first day. But Yue informed us about that beforehand. The location close to gare de l‘Est and gare du Nord was great for us, still the apartment is located in a very calm street and at night we didn‘t hear a noise. All in all an amazing stay! We are happy to come back again!
