We had a wonderful stay at Tiago's !!
He was so thoughtful and kind, he gave us his best addresses and good tips for restaurants and places to see !
The appartment is so cute, well appointed, but must of all it's in the center of Lisbon, you can do everything by walk.
You have bars, restaurants, supermarket, bakery near by, the only "cons" can be the noise at night, but it's totally understandable cause you have bars down the building, and it's manageable !
I bet you will have a fantastic trip around :)
