Nuno's flat is simply perfect. It's both practical and charming.
It's located in a very central neighbourhood, making it easy to visit, go out, etc. It's also quite roomy and well equipped, so you'll feel like at home.
The flat is very bright during the day (in May at least) yet chill during the night. The view is outstanding and having a drink on the balcony in the evening is a must-do.
What's more, Nuno is a very welcoming host, and he is really keen on making your stay pleasant.
My bet is you won't be disappointed.
