Great location in Roma Norte! The apartment was easy to find, easy to check in & very clean.
The wi-fi was great as we worked from the apartment for a few days. Having 2 bathrooms turned out to be very handy too as many of the other reviews have said. As mentioned, the location was great (so many great restaurants were in walking distance). Communication with Setsuko was really great too - she was very on top of communication prior to our stay and checked in often to make sure everything was ok.
One thing I would recommend is bringing enough toiletries (shampoo, conditioner, body wash) as there were none in the apartment. Alternatively, the corner stores had these items for really affordable prices in smaller sizes, so it really wasn't too bad...just be sure to go before you hop in the shower!
