Quick and easy. Denise was extremely responsive and helpful, and their driver service is worth it because the walk would have been tough (across a freeway overpass and through a tunnel). Not much to say about the room - it was what I needed for an afternoon before an early flight out. Hot water in the showers?
The biggest downside was the strong a nauseating smell of cleaning chemicals in the room when I arrived. It didn't really fade, but I guess I got used to it enough to sleep. I let the hosts know so hopefully that changes :)
I will encourage anyone staying here to check out the neighborhood. It is decidedly not touristic, but is crowded and bustling. I went to a movie ($3 ticket) in a 5 min Uber ($2) and the theater felt like sold out sports arena. If you're a bold eater and looove tacos, hit up Taquería Los Abogados. It's a quick walk, and you'll be treated to super authentic tacos and environment. The tongue is their specialty, and it was good (served in huge slices), but I would recommend the suadero...wow. Good ice cream across the street at Montparnasse too.
