I stayed at Marcos'apartment for a few days with a friend and it was truly a lovely experience! The flat is big, bright and clean with a terrace overlooking the sea. Our room was spacious and quiet. Location is perfect, very close to the Alfama's most famous streets as well as Graça neighborhood. There was a very cool tapas restaurant just around the corner. Marcos is a great host, very available and friendly, he answered all of our questions and even lent us extra towels to go to the beach. And the included breakfast is super nice. Definitely recommend for a relaxing stay in Lisboa!
