Kate was very helpful before and during the stay, always promptly replied. The apartment is as described, very small but cosy and well equipped, it is fine for a small stay but I wouldn't recommend it for more than 2 nights. The location is ok, about 30min walk to the center, the closest subway station is about 15min. Few things that weren't that good: the curtain doesn't cover the window very well, so there's a lot of clarity as soon as the sun rises, there's no place to put your clothes at, so you need to keep it in your bag, and the place itself wasn't that clean, there was a strange smell when going inside. Other than that, it's a good place to stay for a few days and explore Lisbon.
