My friends and I loved staying at Carlos's place. It's a beautifully-decorated, funky duplex in the old part of Lisbon. Carlos was extremely responsive before and during my trip. He allowed me to check in early, and I was met by his lovely friend Antonio who gave me access to the apartment, showed me around, and sent me a list of good restaurants. I would not hesitate to stay there again the next time I'm in Lisbon.
