Tiago and Sonia are the best hosts I have ever encountered. And they are so professional! They accommodated us with no problem when our flight was delayed and we got in at almost 2:00 in the morning. They also gave us a wonderful overview of Lisbon with maps and told us how to get to different tourist attractions even though it was the middle of the night.
Their apartment is beautiful, clean, had a nice smell and was just as pictured. The air conditioning was pefect, bed was comfortable. We have no complaints. The location is pretty good. We walked to Alfama and Bairro Alto in about 20 minutes and the metro is pretty easy to take.
