Our stay here was lovely! Annie and her husband were flexible, courteous and very positive. Staying here was lovely. If you aren't visiting from far away, I may suggest bringing your own pillows if you are used to many/thicker ones, but it was nothing unbearable. The room is plenty warm and there was always hot water. There are basic amenities (soap, body wash, shampoo (no conditioner). Note that when we visited, there was instant coffee/tea available, and a french press for making coffee, but you would need to bring your own/buy coffee if you wished to use the french press. A variety of cooking supplies/ingredients were around and made breakfasts/late night snacks a bit easier.
On that note, the location was great, and we went to a few places on their suggestion which turned out well. We would also recommend the brasserie right across the street if you want a more expensive meal--it was lovely! Most tourist spots were an easy train ride away, with multiple stations close by to pick from, and the walk is not too bad for those who enjoy seeing the city and staying above ground while they are traveling :)
I'd highly recommend a stay here for any friends and/or family staying in Paris :)
