Martinho and Antonio are without a doubt the best AirBnB hosts I have had the pleasure of staying with.
I had been in Lisbon on business the week before and had to check out of my hotel before I could check into their apartment, so Martinho came to hand me the keys in person at the hotel and take my bags to the apartment himself.
Once we arrived, the apartment was gorgeous - photos don't do it justice. They made every effort to accommodate us, with some snacks and drinks left behind, and helpful tips on what to see and do. The place is immaculate, and wonderfully homely while also very stylish. Location wise, it's really easy to get into town too, and there are some nice local restaurants if you don't fancy the short walk to Barrio Alto.
I would absolutely stay again!
