I stayed at the Welcoming Dragon B&B for nearly 2 weeks and I really enjoyed it there.
The place is spotless. There is a separate bathroom for guests, so plenty of privacy for all. There is fast internet WiFi. Breakfast is great. Lots of good places to eat cheaply nearby. And it is close to 2 metro lines.
The best thing though, is that the owner, Philip, makes everyone feel so welcome, just like part of the family. You can sit and watch tv or read a book or he will help you if you want to go out somewhere. He has a tourist industry background, and really knows the ins and outs of Paris.
I recommend this B&B to anyone who is coming to Paris for a few days or even a few weeks. It is a terrific way to get started in Paris, much better than you can ever get in a hotel.More
