This is a fabulous place for a couple spending a couple of days in Lisbon. I definitely wanted a place that is quiet and you do find quietness and a good night's sleep here. Not only is the alley quiet but the windows are double-glassed and do keep out the noise. The location is good, only minutes from the tram stop and short walking distance from the flee market, Praca do sol and Alfama's wonderful nightlife.
We stayed in Lisbon for an entire week with our one year-old and for that stay the apartment was too small. There is no space to put a bigger piece of luggage and no storage place for clothes. Two pieces of furniture were broken and only holding up because they were leaning against the wall.
Getting in touch with Ana before our trip was hard (we finally called her after sending two messages, two and one week before our flight) but checkin and everything else went absolutely smooth once we arrived.
