Emeline was extremely communicative prior to our arrival, answering all of our questions quickly and in detail. Silvia, the woman who checked us in, was great as well- very friendly, accommodating, and informative about both the city and the apartment.
The apartment looks much like the photos. It's definitely small, but still comfortable. We had to be careful and plan ahead with showers to make sure there was enough hot water for everyone (there were five of us). The beds were comfortable and the kitchen was well stocked. Wifi worked perfectly the whole time we were there.
Unfortunately, the metro station nearest to the apartment was closed, but the next one wasn't too far away, and had two lines, so airport access was easy as well.
