Lourenco is an amazing host, he is ready to help, answer questions and give advice. The flat is located perfectly, very close to metro and not in the very city centre with tourist crowds, so it is pretty quiet. But you can easily get to the centre on foot. 28 tram has stops not far from the place. The flat is very cozy, got everything you can need. I travelled alone, so I felt very comfortable. This is the flat I would like to return back again in Lisbon.
