Carlos and Kristina were the best hosts ever. I've stayed at many Airbnbs and I have to say that they were the most accommodating. We had to leave at 3:30am and Carlos woke up to call a taxi for us! I really loved the location in Alfama. You're right in the middle of a charming part of town that attracts tourists but doesn't have the same hustle and bustle of downtown.. Unlike some parts of downtown Lisbon, I felt very safe even at night. I loved strolling throughout Alfama in the evening and you could hear music from all the "Fado" music playing in the restaurants. The apartment is located close to one of the main train stations (Blue Line), which also includes a Lisbon Welcome Centre (where you can pick up a Lisboa Card). When I visit Lisbon again, I will book at Carlos' place again. If his place isn't available, I will definitely stay in Alfama again.
