This apartment was fantastic - the space is so cool and stylish! I loved being around all the books, and hanging out on the comfortable couches. It is a bit old, and could do with a bit of a refresh, but it didn't take away from the experience. It's on quite a busy street, but if you keep the windows closed, it's not too noisy. The view especially at night is great with the floor to ceiling windows.
Location-wise it's perfect: it's within walking distance from a lot of the beautiful neighbourhoods and great restaurants, and there's a subway stop just outside the building. There's a mini-Carrefour a block away, which is quite handy as well. There's also a big shopping mall across the street, where you can change money or buy a SIM card.
Communication-wise, Diego was very responsive and flexible with our late check-in and late check-out - thanks!
