When we arrived to Tiago's house we were received by Bernardo (a friend of Tiago), a funny and kind boy that has shown us the apartment . The house is the same as you see in the pictures, a nice and comfortable apartment where staying for holidays but maybe also for work (I loved the desk just near the bed). The only remark is about the bedroom that was a bit wet, but I've also to say that there is a dehumidifier that we never used, maybe it would have been useful to solve this problem, it's my fault that I didn't try it :)
Lisbon is a wonderful city, plenty of historical sites, plenty of life and nice people. Tiago's house is located at 15 minutes far (by feet) from great quarters like bairro alto, baixa and chiado and only 5 minutes from rossio and Avenida da Liberdade (where to catch the metro for every destination included the train station to get to the beaches). Don't miss a night in bairro alto if you want to really live lisbon.
Thanks Bernardo, thanks Taigo we had a great holiday, we hope to come back to Lisbon again!
