This 4th floor walk-up is in the heart of the Alfama District - a wonderful location for our first trip to Lisbon. We were picked up at the airport by a lovely guide who showed us points of interest en route to the unit, and our hosts were very responsive via email. There are numerous airbnb rentals in the building, and the 24-hour party people had access to the shared courtyard. Fans (turned to high) drowned out the noise in the front bedroom but not so much for the rest of the unit. The apartment is modern, clean and comfortable, but the building is old - as is the plumbing - which imparted a funky odor.
