Antonio's flat is nothing short of perfect for a stay in Lisbon. It's in a rather centric location to which cars can easily get and it's on the ground floor, which makes hauling luggage a dream. The flat itself has modern fixtures and the space is efficiently distributed. The bedroom window faces towards a courtyard, so unless there's a party going on it's perfectly quiet at night.
Antonio himself is a great communicator and has a very clear and easy-to-follow set of instructions for how to conduct check-in and check-out.
I know where I'm staying next time I come to Lisbon.
