Pros: The location is great, the area is pretty walkable with bars, restaurants, Louvre within walking distance! The apartment is easy to find and Sonya is great with communication. The price was decent given we wanted to be in great location, but since metro is great, one can live in another area as well. The apartment is fine to just come and crash but definitely not like a vacay place you'd want to stay in.
Cons: The apartment is very tiny with limited space particularly in the bathroom (probably that's what you get in Paris!), the bathroom floor takes time to dry, the wifi didn't work at all (although Sonya offered that her daughter could fix it if we call her but I didn't want to trouble her and had read previously on reviews that wifi is an issue; given am a software engineer, I also tried all hacks to fix it but nothing worked), you have to take luggage through stairs till the 4th floor (there is no elevator as it's an old building with a bunch of retirees living there). There was no body wash in the bathroom (only shampoo and conditioner) which was surprising so we had to buy one from Sephora. Also, for 6 nights only one towel per person was provided which is hard given there is hardly any sun in the apartment, so you can't really dry it.
