Francisco's apartment was really clean, stylish and well stocked with the necessities you would need for a stay. If you're worried about carrying heavy luggages up the stairs to the apt, don't need to as the house is only about 15 steps from the ground floor. Very manageable! I was really impressed with the check-in process - basically there's a key box outside the building and you just need to key in a code to retrieve the keys. It works the same way for check-out. Very efficient and safe.
The apartment is located in Belem and is ~10-12 mins walk to the famous Pastéis de Belém, so it is really convenient if you are planning to do most of your sightseeing in Belem. One thing to note is Belem only has a train station and not a metro station, so you would have to take a short train ride then change to the metro line. It depends on your itinerary; the location might work or not work for you. We initially found the apt to be situated in quite a remote location (not near to the city) but later realise that it is not a big problem as Belem itself has quite a bit to offer and it is easily accessible everywhere by Uber.
Also, the host himself is very responsive and helpful! (:
