What a lovely little apartment! Small, but very cute - great book collection! For us, it was perfect - just a few minutes by Metro from the Eurostar terminal, so incredibly convenient if you are coming from London. It was also very quiet, despite being in a lively area. Plus, the bed is very comfortable, so we slept well :-)
The location was also excellent for all the main sights - we walked EVERYWHERE, and discovered so much of Paris we hadn't seen before. And Zoe was really easy to communicate with, so all-in-all a perfect stay!
