The location of the apartment is amazing and Francoise was wonderful in her welcome. She gave us a little walk about the neighbourhood and suggestions for restaurants and grocery stores. You can walk to many of the main tourist sites from the apartment, so we didn't have to take the metro or taxis as much.
We were also allowed to check in earlier and she was nice enough to get us a some snacks ans juice.
As others stated, there are some flights of stairs to climb and though it was a little difficult with the suitcases, they were manageable and we didn't have problems. The apartment was well equipped and homey.
It was 4 friends and we were very comfortable and would definitely recommend this apartment.
