Overall we thought Charles’s place was very good. The unique touches in the apartment were a pleasant surprise and the hospitality was great. There are a couple things that may be ok for some, but not others.
1) at least by US standards, the description of two bathrooms and two bedrooms is not accurate, in my opinion. The bathrooms consist of one bathroom with a toilet, shower, and (tiny) sink. The other is a bath and sink in the master bedroom (no second toilet). The second “bedroom” is really small. The convertible sofa bed is only good for one person or two young children. My two teen daughters decided one would sleet on the couch and one on the bed.
2) Also, note that there is no air conditioning, which is correctly stated in the listing. If you like to sleep with the windows open, note that it is very loud at night as the apartment is situated on a busy street. If you are a light sleeper and do not have earplugs, you may have trouble sleeping.
If the issues above don’t bother you, I would recommend the apartment. The views are fantastic and It is situated close to the metro and Marais (without the Marais prices).
