Staying at this Airbnb was really nice! It was really affordable and in the centre of downtown Lisbon, so you could walk to many activities and restaurants. The host was so kind and friendly, always responsive and offering recommendations for the local area. Plus, this Airbnb has the advantages of being hostel-style so you can meet new people, but also has doors that lock so your items are secure. You can even store your luggage before or after checkout for a small fee, which was so helpful when I wanted to explore the town without carrying it around! I highly recommend staying here!
To add: As with any Airbnb, bring ear plugs - noise from elsewhere is out of the hosts control but can happen sometimes. Overall it was quite calm. :)
