The location for this apartment could not be better! It was walking distance to Notre Dame--or an easy bus or metro ride to any place in the city--thank you, Google maps. But most especially because it's adjacent to some several excellent cafes and specialty establishments clustered around a church garden and square, a terrific boulangerie--so good!, delicious fruits et legumes, and every other service you may need--ATM, laundry, grocery. We really enjoyed our visit to a neighborhood where Parisiens live and work, rather than a sterile hotel.
Re laundry--the dryer in the apartment wasn't working, which was critical for us as we'd been traveling in other cities and had minimized packing. Sarah and Romain paid for us to receive laundry service from around the corner, which was much appreciated. The communication was timely and excellent.
