I stayed in João's apartment for about a week. It is very spacious, well decorated, and had everything I needed to enjoy my stay.

The upstairs has huge windows, great for people watching, but a reflective coating so folks outside can't see in. The kitchen was well equipped for cooking, and even had nice containers for leftovers (something I rarely find in rented places). The downstairs has an office area, bedroom and bathroom. The bathroom has a full bathtub, perfect for hot baths after a long conference day. There was a hair dryer and iron + ironing board, which was very convenient.

The location was great, with a short walk to the Marques de Pombal, and metro stop, and right near the start of the Agenda da Liberdade street, which has lots of food and shopping. The area felt very safe (important for me traveling alone). The wifi was reliable and fast. João gave multiple ways for us to meet up, and was very helpful for coordinating check-in and the usual questions that come up around holding bags before official check-in and after official check-out. He always responded very quickly to questions.

Overall, I would recommend this apartment to anyone, it was safe, clean, conveniently located, and had everything I needed for an extended stay.
