We chose Michelle's apartment mainly for its situation and to have more room than in a hotel as my husband and I were traveling with our 12 year old grandson. The address could not be better, on an attractive street by the Seine, handy for all the main sights. However, the actual space is situated in the interior patio of the main apartment building in what looks like a converted porter's lodge. The approach is through a dark, dusty corridor and the patio had buckets and general mess scattered around. This is obviously not the host's fault, especially as the building was being painted, but we did find the ambience a bit depressing.
The actual apartment was very clean, pleasantly decorated and well kitted out with good quality appliances etc. Michelle also provides coffee, tea, a complimentary bottle of wine and lots of useful Paris guides. However, it is small, about the size of a good hotel room and, once the sofa bed is pulled out, rather cramped. Certainly you would need to be very good friends if four of you go! The bathroom has a good, walk-in shower but the loo is in a sort of cupboard, which could prove difficult for anyone with either claustrophobia or a few extra kilos.
In my opinion, this is a great location and Michelle is an attentive hostess. Once they have finished painting the building's entrance, things will be better. Although I realize that Paris is one of the most expensive cities in the world, I think that it is expensive for what it is, especially as the cleaning fee is steep and there is an extra 20 euros charge for a late check-in (we arrived at 20:30), payable in cash on arrival.
