My partner and I spent 4 nights in Nuno's place and it did not disappoint.
The apartment is about 10 minutes walk from the metro station or you can walk to the main area of Lisbon within 15/20 minutes.
Check in was smooth and Nuno was very kind and let us check out later so we didn't have to wait around for our bus. Nuno communicated very well and responded very quickly to any messages.
The apartment is spacious and had plenty of towels, blankets, pillows etc. There was always hot water for the shower and washing dishes. There is a hob with pots and pans for cooking, a microwave, kettle, toaster and a Dolce Gusto coffee machine (Nuno kindly left some pods for us to use)
I would reccomend staying at Nuno's place. It is in a safe, central area and Nuno is a fab host!
