My partner and I had a wonderful time at Didi's place, which is located in the heart of the lively Bairro Alto neighborhood. The apartment is super comfortable, cozy and beautiful, and you could hardly have a more central location to explore Lisbon. On top of that, Didi is probably the most helpful and friendly host I have met on Airbnb - and he really wanted to make sure we were having a great time in town :) in our case it was a mix of work during the week, and simply enjoying this wonderful city during the weekend.
It should noted that the neighborhood is very lively at night (which was clearly stated in the listing), so if you have a light sleep it's better to wear earplugs. In our case it did not really bother us as we are heavy sleepers :)
Overall, we definitely recommend staying at Didi's place for your next travel to Lisbon! We would come back anytime :)
