If you're going to Lisbon I would 100% recommend this airbnb. Firstly, the hosts Camilla & Cynthia are absolutely lovely. They are more than happy to help you with any questions you might have and have a list of great places and restaurants for you to check out. Secondly, the apartment is in the incredible neighborhood of Alfama which you could just get lost in for hours. It is also a very good location for hopping onto public transport to take you anywhere and everywhere in Lisbon.
The house is sparkling clean and is in a beautiful neighborhood and managed by beautiful people, I honestly couldn't think of a better place to stay.
