Mario's BnB was my first Airbnb-stay and I think we made the right choice. We had a private room with a double bed and fresh towels, we could use. Sadly our room was on the side of the street, so it was a bit loud. The bathroom could have been a bit cleaner but it was acceptable. Next to the kitchen there was a really nice terrace to sit on and relax. The greatest thing about our stay was the location of the BnB and Mario's App! We were able to see the whole city in a few hours without getting lost!
The breakfast at Nata Lisboa was great as well - especially their self-made ice tea!
Thank you for your efforts, Mario! :)
