This little flat in tucked in a lovely narrow street in Alfama is very charming and slightly removed from all the activity, so while you still get noise from tourists going up and down the street with suitcases or other, I think it's probably quieter than other spots in the neighborhood. it's certainly very central and perfect to visit Alfama and beyond. it's a few steps to tram 28 so a nice way to start the day when visiting.
The flat is perfect for one person or a couple as it's a loft but the sofa bed is very comfortable (probably best for 1 than 2).
Lots of natural light in the room and a bit less in the living room and kitchen, will equipped for long stays with a coffee machine, toaster, cooking gear, and a washing machine. It also has a large TV which you probably won't have time to watch as there's so much to do around Lisbon. The water in the shower has good pressure and is hot.
Antonio is a very welcoming, generous and helpful host and made it all very easy and pleasant. I definitely recommend staying here! Obrigada Antonio!
