Location:
Agnes' place is in a great location. A few mins walk from La Fourche station, and you can get anywhere in Paris from there, and nearby to a mini-mart for supplies, or restaurants for eating out. Montmartre is within walking distance as is the Moulon Rouge area.
Apartment:
The apartment was clean, functional and quite large for Paris although a little tired and could use a renovation. The sun pours into the living area in the morning and really brightens the room. I stayed for only 3 days and didn't use the kitchen much, but everything is there. The washing machine does a great job and Agnes has an amazing steam iron. Its a 4th-floor apartment, but there is a lift that will take one person and their suitcase, so if you have a few of you and a lot of stuff, expect to take a few trips.
Communication:
I was unsure of when I would arrive, this made it difficult for Agnes to arrange her person to meet and greet me, but she worked with me, and was constantly staying in touch. I had no problems getting access to the apartment when I needed to even though I arrived quite a bit later than planned.
Value for money:
Depending on your expectation, Agnes apartment is good value for money. However, if you are expecting a 100% perfect apartment in Paris, this is not for you, but be prepared to pay a lot more if that's what you want. I was in Paris on business and usually stay in Hilton class hotels, so I don't think I would stay here on business again, but if I was in Paris on holiday, I certainly would.
