This place is everything you need and more. The host is extremely welcoming, answers in real time and the place is spotless. The beds and pillows are outstanding! In terms of location, it is a short and mostly plain walk from Martim Moniz, where the tram 28 line starts and will take you to all tourist spots.
Extra tip: purchase the day pass for public transport (less than €7) and you can hop on and off all public buses, including tram 28, to go everywhere and avoid the steep climbing to reach most landmarks.
If this is your first time in Lisbon, this city will take your breath away! Don’t forget to pack your comfy shoes.
