This place is modern and cozy and in an amazing older neighborhood, Alfama. There are tons of small, family run bars and restaurants tucked away into small winding neighborhood streets that felt like quintessential Lisbon to me. It's about 15-20 min walking to the main city/downtown center and you can even take a walk there by the water if you'd like. It's an easy walk to Tram 28 and the main center where you can visit all the shops, bakeries, amazing restaurants or the train station where you can take a day trip to Sintra or Cascais.
I was with my cousin for half the time, then by myself the last half of the trip and I felt super safe walking around the area at night. Everything is well lit, people are friendly and stores and restaurants are open pretty late and people are out and about.
There were initially a few small miscommunications about the extra bed as well as the lack of coffee machine (which was heavily promoted in the Airbnb listing but then wasn't even present in reality), but the hosts Pedro and Patricia remedied all my concerns quickly and made sure I was very happy and comfortable. Even with an extra blanket the place was quite cold at night time, I would highly recommend they provide a small space heater for the bedroom at least and maybe a rug or two at least in the Autumn/Winter.
Even though the place wasn't 100% perfect and not exactly like the photos, the hosts were wonderful and I adored the lovely neighborhood so much I would definitely come back and stay for longer in a heartbeat. Highly recommended!
