We had a great 5 nights at Barbara's apartment. It is in a great area, with a small supermarket and boulangerie located around the corner. Eva was very welcoming and made check in easy (even with my limited French and her limited English).
The apartment had plenty of space for our family of 5, there was enough hot water for all in the morning and the kitchen had all we needed to have simple dinners at home.
The beds are comfy and the whole apartment was clean (I didn't feel the need to wash plates and cups before use). And the kitchen knives are sharp (so nice to find)!!
The only down side is the noise from the cafe downstairs. It is open until 2am most nights, and the patrons sit outside eating, drinking and talking until late. With the windows open it is noisy, but cool for sleeping. With the windows closed it is quieter, but the rooms warm up quickly. This is obviously out of Barbara's control, but worth knowing. If you think that this will worry you- bring some ear plugs, or book elsewhere.
Overall we loved Barbara's apartment, and look forward to staying again the next time we are in Paris.
