Whether you plan to be in Paris for one night or a week, I can not more highly recommend that you try Veronique's place. She is an extremely gracious host, and instantly put you at ease. The apartment is perfect for one, or more guests, and you'll immediately feel the sense of being in a loving home. Exceptionally well kept, but very warm. The space has everything you need, comfortable bed, lots of available light, a complete kitchen, sitting room with writing desk, complete bathroom with shower, a washer, iron, and even books to snuggle in with on a rainy day. There are light snacks and a coffee maker + tea - the market a few doors down when you want groceries.
Everything you need can be pretty much found on your street - market, pharmacy, cafe, boulangerie, flower shop, hair stylist - though the apartment remains quiet inside. You are protected within a courtyard from the street. A short block to the park where outdoor market is held, and the other way to the bank, and Main Street, where you can walk to the sights, catch a bus, or taxi, or metro.
It was perfect for me on my own. I felt safe, and people around were happy to assist me me with my French. :)
I look forward to a return!
