I just had an opportunity to spend some time in Natalia's place and here are my thoughts:
PROS
- super responsive host; I had a small issue with the coffee machine it was fixed the same day. I really appreciated that. Natalia was also very nice re the check-in I was able to check-in early and this was also very appreciated!
- excellent location, supermarket around the corner, plenty of restaurants, 3 metro stations near by. This is a very popular area with plenty of shops
- flat has everything you need and internet was excellent during my whole stay and I used it a lot!
CONS
- as others have said previously the place is really tiny with the bed and some space to move around it. In retrospect it was a bit too small for me for my long stay but I managed and got used to it. It is probably not a big deal if you intend to spend most of the time outside and use the place to sleep.
OTHER
- the place can be noisy with a couple restaurants and the boulevard Montparnasse a few m away. Strangely enough it did not really bother me and yet I am very sensitive to noise. It never prevented me from sleeping and even when a few loud people woke me during the night they move on and i fell back asleep right away. So I do not want to put that with the CONS.
In summary the only drawback is the small size of the flat but the host makes up for it
