About the place: Fantastic unbeatable location, right in the middle of Chiado and 5 minutes walking to the metro station. Many restaurants and shops around the area. Close to Bairro Alto, Chiado, Baixa, Alfama.
The apartment is fully equipped with everything you could possibly need. All kind of plates, glasses, containers, cooking utensils. Nice sofa and bed (not that hard, it's actually comfortable), TV on living room and bedroom, good wifi connectivity (ideal if you need to work). The place is bigger than it seems in the pictures!
The host: Diogo's is an excellent host, he was patient to wait for us when we were delayed at the airport. He gave us a lot of tips about Lisboa, recommended restaurants, bars, sights and even day trips.
I've stayed in many AirBNB accommodations and this one by far the best welcome pack. Coffee, tea, cookies, peanuts, salt, sugar, cheese, toiletries, etc, etc. Everything waiting for us as if it were our home.
Minor comment: The street can be a bit noisy if you're a light sleeper, since it's a very lively area and there is a "pub tour" that passes around 1:30AM. But even in that case, the double glassing in the bedroom helps a lot.
I highly recommend this apartment and the host!
