The flat is well located, just a few steps away from the bus station and the Arc de Triomphe. To our surprise we didn't know this area is a little Chinatown, there are lots of Chinese shops and ads (which was fun to see in Spain). The flat is quite comfortable, all A/C work, and the Patio comes quite handy for those who like to smoke without having to leave the place.
On the other hand and as an honest review, I must say that both bathrooms could be improved and better cleaned. One of the bathroom showers has a constant leak which has caused the tub to become rusty. There is also fungus on parts of the walls and floors (in both bathrooms) so we had to use our flip-flops every time we took a shower. I believe that this could easily be improved and would make the guests feel more comfortable as one usually never showers with flip-flops at home (or as it is our case, we don't have fungus or rust in the bathroom).
Overall, this was a good stay and Anna was very friendly during the check-in.
