This apartment is a good size for three people. The beds are comfortable and the furniture is nice. The apartment is not just used for renting it is used by the owner so all of their personal items are around. We were there for 4 nights and had room for our clothing/toiletries.
The apartment is on the 6th floor and does have a small lift you can use. The location is great as it is near by two metro lines and a 10 minute walk to the base of the eiffel tower. We were there at the end of July so it was 26-30C each day. Because of the high tempreture we had to have the windows open and the noise from the Metro and traffic is loud. The metro is above ground near the apartment and the noise is definitely intrusive when you have the windows opened. When they are closed there is still noise, but more background noise. If you are used to city noises you will be fine, but if you are a light sleeper or have trouble getting to sleep I would not advise this apartment in the summer.
The host's mother lives in the building and she met us to let us in and show us around. Unfortunately, one day we had an incident with her. It was mid-day I had just had a shower, my husband was napping in the main bedroom and my daughter meant to be napping in the 2nd bedroom. I heard creaking of the floorboards and I called out to my daughter. She didn't respond so I went through the bedroom door and the host's mother was walking out of the 2nd bedroom where my daughter was. She said she had knocked and did not hear a response so let herself in to get a vacuum cleaner from a cupboard. When she opened the door she did not call out at all as I would have heard. This was a complete invasion of our privacy and after that moment I felt on edge in the apartment as she could have come in again at any time. Both Claire and her mother had my phone number, she should have messaged me directly or asked Claire to get in touch so we knew she was coming.
The day before we left I had messaged Claire to say we had to catch a train and we would be leaving at 8am. She responded to my message to say see you then. I waited around until 8:05 and had to leave. I messaged again to say we were leaving the keys, I knew her mother had access to the apartment. I never heard anything further.
