The three of us stayed in Lisbon for three nights and had a very good time. The location is excellent for exploring the city as well as for going to Sintra (the station is about 5-10 mins walking distance). There are many little shops just around the corner where you can find everything you need as well as a ‚must go to‘ for everyone who loves beer: The Queen Ale. Check in was easy and flexible (we would recommend getting off at Rossio instead of Martim Moniz if you take the metro from the airport). We were greeted by Pedro's father Carlos who showed us around the apartment and gave us lots of extra information on the house and the city. :)
