This is a cute little apartment right in the centre of one of the loveliest parts of town. It's not big - expect the bathroom to be a tight squeeze - and getting upstairs can be tricky with luggage, but the bed is spacious and the main living space is great, with a lovely balcony and shuttered windows that do a great job of keeping out all the noise of Lisbon nightlife when it's finally time to go to sleep!
Nelson includes his own personal guide to Lisbon, which we found to be a good read, and the apartment itself is very close to several great little restaurants and bars, and a few minutes walk from the riverfront and the awesome Lisbon food market.
Really the only downside is if you have a heavy-footed upstairs neighbour, thanks to the wooden flooring, but it didn't spoil our enjoyment of the flat and our Lisbon experience.
