We loved our stay at Duques Villa. The apartment was super stylish, large and comfortable and the hosting was fantastic - so friendly and lots of helpful tips.
As we were staying in Lisbon for a week and had a car we deliberately wanted to be somewhere that was outside of the historic centre, but within walking distance. In this regard Duques Villa was the perfect location. It is around a 45 min walk to the centre of the city, maybe 20 mins to Alfama.
The location is cool, because it allows you to get a sense of the local character close to the port, which is a bit more 'real' and 'gritty' than the tourist spots. So if, like us, you are happy to walk the location gives you the best of both worlds. Its the perfect base for a longer stay in the City, and Lisbon is so much fun.
Definitely recommended, and we'd happily stay again.
