Carlos's apartment is super amazing - sunny, comfortable, clean, well equipped and rather quiet. Everything is just like in the pictures and description, maybe even friendlier. The view from the apartment is truly exceptional. The castle, the port, Barrio Alto's bars and restaurants are all 10-15 minutes walk away. Metro stations Rossio and Martim moniz are 3 minutes.
Carlos was a perfect host, the communication has never been better. He was already waiting for us in the apartment when checking in, and he was kind to pick us up when we lost our way in Lisbon's tricky little streets.
He provided us with lots of detailed restaurant recommendations, which appeared to be correct. But beside those, we enjoyed the African restaurant Aziz's place too, just below the apartment.
Thanks again, I'll definitely contact you Carlos on my next trip to Lisboa. :)
