The Tiago's apt has a great location (Bairro Alto - five minutes from the Manteigaria) and it's really in the Lisbon old town center. Tiago was a nice host and he even gave us a list of nice restaurants and details about the neighborhood. The apt was clean and adorable. One think I should mention is since you are in Bairro Alto heart, this is a "party" area with several bars and restaurants, the noise may bother a little (even if you're on the 4. floor). But the rest was great!
