The location of the room with private bath is quite close to the airport (€3-€4 Uber ride) (it’s about a 5-8 min walk to “Encarnacao” Metro station which is one Metro stop away from the airport. To get to Alfama is about 20-25 mins via Metro as well.
Antonio and his wife were excellent communicators when needed check-in was easy (they will meet you to check-in)
Wi-Fi in the room was strong, there was a coffee maker with pods provided and sugar, a mini fridge, cutlery and plates in the room along with body wash in the bathroom. The air conditioner cooled the room quickly, there was also street parking available if one had a car (parking in Alfama is awful).
I am leaving a four instead of five star review because the bathroom had a putrid smell coming out of somewhere (vent?) Every so often one could get a whiff of it from the room, when using the bathroom it was pretty strong. For light sleepers be aware the walls (as are most homes in Lisbon) are quite thin, one easily hears muffled conversations, the sound of movement by other guests leaving and arriving.
There are rules posted for guests but during my last night, someone was up causing a ruckus at 3a.m-ish. I informed Antonio about this and he was responsive.
