If you are going to Lisbon, then I highly recommend that you stay at Ana and Fatima's apartment. The apartment was definitely one of the nicest I've stayed in. It was very clean and had everything we needed. They even had a bottle if wine and some delicious tarts for us when we arrived.
Ana and Fatima were very helpful to us. They called to check the availability of restaurants, and called a taxi to meet us when we had to go to the airport. The location was perfect in Alfama, with many sights to see and good places to eat. I will recommend staying at Ana and Fatima's apartment to anyone who wants to go to Lisbon.
