We stayed at Michel's flat for four days - myself, my husband and my adult son. We arrived in Paris before the 3 pm check-in time and Michel was very accommodating with letting us check in early. The flat was very clean and the beds extremely comfortable. There was plenty of room for everyone. The kitchen was great to have - and we used it for breakfast everyday - as there is a grocery store minutes away to purchase anything you need.
It was great to have two bathrooms - each with it's own shower.
The flat is convenient to the metro - it is only about an 8 minute walk. There is also a very good neighborhood Brasserie a few blocks away.
I very much recommend this flat - a great place to stay while in Paris!
