We had a great time at Sergio’s. Great location (5 minute walk from the subway line and IN the historic Alfama district), very safe (locks on the bedroom and bathroom, and autolocking front door), very clean, and plenty of amenities including a fridge, BBQ, stove, hair dryer, iron, etc. The bathroom is not attached to the bedroom but we did not have to share with the other unit, we got a bathroom all to ourselves that only we had the key to. Overall great experience, definitely will return here if we’re ever back in Lisbon!
