Stayed at Antonio's place for three weeks... Would stay here again for sure!
Perfect location for visiting... 3 minute walk to Rossio Square... 5 minute walk to a bigger grocery store. 5 minute walk to three different metro stations, on two different lines. 15 minute walk to the river. Nice and quiet neighbourhood at night, and also many ethnically/culturally diverse people and restaurants immediately by. 20 minute walk to Bairro Alto if you want to go to the party part of town. Air conditioning which is great in summer, and washing machine/dryer for laundry.
Antonio's communication was great and he was very helpful when he picked me up from the airport... took time to show me maps of Lisbon and even had a pastry treat waiting for me. Very attentive and quick to respond when needed while I was there.
It is located at the top of a hill and on the fourth floor, so your legs will get a work out... this was a good thing for me, but it will be an issue if you have mobility concerns; however, so will all of Lisbon!
