Wonderful little studio in Alfama - we loved the location. Place is small but has all you need. Clean. Only issue was the noise from other floors- people entering the stairs at all hours of the night/morning and can hear conversation and steps from above floors. Used ear plugs on the final night which helped a bit.
But I guess the building is in an old neighbourhood and these traditional houses had poor sound insultation so can’t be helped.
Also hot water runs out quickly So have to schedule your showers at separate times. Other than that it was a great experience in a wonderful part of Lisbon. Hosts were wonderful and helpful.
