Excellent Airbnb in the old part of Lisbon, about a 6-10-minute uphill walk to the closest metro station. Definitely an experience staying in Alfama. However, please note (1) tram 28 is rarely on time and there is no timetable as such, so don’t expect tram 28 to be a replacement for metro (2) if you have weak legs, you may wish to book in the newer parts of Lisbon (rebuilt after the 1755 earthquake) which are flatter, as the streets in Alfama are very very very steep.
