We had initially booked something more central (Arr-2 / Louvre area) but when that fell through, we booked this apartment in Arr-15. We were initially hesitant as all our previous stays in Paris had been more central, but were very, very pleased with this apartment and the surrounding area.
The apartment itself is in a very secure building, only 5 minutes walk from 2 metro stations (near Metro Pasteur, on the Nations line). It is also only about EUR 10 - 12 taxi ride from the Louvre area, and only about EUR 6 taxi ride from the Eiffel Tower (walkable in about 20 minutes). The apartment is in a quiet street (no traffic noise), although during weekdays has a little bit of noise from the school children who walk past to attend the school at the bottom of the street. At the bottom of the street (western end) there are quite a few shops, which include Cafe Basile which is a great place for the family to eat (good menu and wonderful staff), and a good place for a beer or wine at the end of a day of sightseeing. Location-wise we cannot fault this apartment.
The apartment itself has three separate bedrooms, which can comfortably accommodate 6 people. The rooms aren't overly large, but are sufficient. There is also good cupboard space for clothes, cases, etc. The apartment has all the necessities including iron, ironing board, clothes washer/dryer, and dishwasher. The lounge/dining area is slightly on the small side - but quite normal for Paris. Kitchen is galley style but well kept and functional. There is one main bathroom, but a second shower located in a vestibule off the hallway (it looks odd, but is very functional with excellent water pressure). There are two toilets - one in the main bathroom, and one in a seperate room off the hallway. Overall the decor is beautiful - exactly what you would expect from a French apartment for this budget range. Well done to the owner for the presentation of the apartment.
Upon arrival we were greeted and shown around. There is also a book left on the table containing tips about transport, shops, and restaurants in the area. A very handy book, which we used several times. I would not hesitate to recommend this apartment to anyone considering a stay in Paris - it has a great location, is well kept, and is managed by one of the nicest guys I have ever met. Thank you Mathieu for a wonderful stay.
