I spent last 4 nights of my 8 days trip in Portugal at Joana's apartment. Her husband Antonio welcomed us staring from the window and made us a quick intro about the house and city.
After experiencing hilly Lisbon in 5 days I told myself that I couldn't imagine a better location. Thanks to the atmosphere Joana and Antonio created we felt like home. In spite of its central location it was totally silent in bedroom. Kitchen was well equipped and big enough to prepare your own food. Light in living room can be simply adjusted. Check-in and check-out were very straightforward. Library was full with valuable books and brochures about the city.
I will recommend this place heavily to all my friends who will visit Lisbon.
