My friend & I just stayed at Nuno's for 3 nights for a city break to Lisbon. Nuno was super helpful from the get go, he sent loads of helpful information on how to get there from the airport and he was there in person to check us in and give us all the info we needed. The Airbnb itself is in a great location, with lots of nice places around to eat and drink and great access to everything by tram, bus or on foot (ubers are also super cheap). Inside it's cosy but has everything you need, even a coffee machine. The only negatives were the bathroom (everything gets wet and stays wet too!) - we used the mop after every shower to try and keep the floor dry-ish, the noise at night is fairly loud so recommend taking earplugs (also there were often some unsavoury men hanging around outside) and if you get wet your clothes will not dry (we got caught in torrential rain on night 2 and by day 4 we had to pack our clothes still damp, despite having the heater on to try and dry them). All in all a brilliant stay - perfect for 2 people - and we loved Lisbon!
