We had a very good stay at Renato's apartment.
He wasn't there when we arrived but it wasn't a problem. He had given us all the information we needed before and we were able to arrive safely.
The apartment is very well located, the metro isn't far and you can even do everything by walking. The apartment is good for a short stay and the bed is comfortable. It was just enough for us.
SO, we had a wonderful stay in Lisbon.
