I would not only recommend Narjes' B&B, but would happily go back again next time I'm in Paris. Knocked off one star for check-in, since it wasn't as flexible as I would have liked it to be, but didn't have to wait too long, and it went very smoothly. I also could have been more specific about time of arrival, not not totally your fault - just a detail that I wasn't aware of.
This is a private room and a private bath in their home, but I never felt like I was in their way, or they were in my way - granted that I was out for the greater part of the day looking around the wonderful city.
The bedroom, and bathroom are both large and spacious, and comfortable even for 2 people (I was traveling solo). The view from the balcony is AMAZING, and the pic on their listing is not a fake. WOW! I was happy to sit in the balcony early morning, and late night - just amazing.
Last but not the least - location is really great too. Couple blocks from a metro station and I was able to get around the city very easily - don't remember exact times, but probably less than 15 mins to Notre Dame/central Paris.
Thanks again Narjes, and her husband (sorry I never got to get his name).
