First, Pedro is a great host. He truly cares that his guests are comfortable. Everything I needed was there and a little more. Communication was prompt and clear and he greets you to make sure you understand how everything works. I chose this stay because the location is at a transportation hub. Just note that it's busy and a bit noisy because of that amenity. Navigating the city is a breeze from here: you can walk to just about anything you want to do (it may be downhill one way, but the return is always up!) and if tired, cable cars, buses or metro are easy options. Cabs and Ubers work, too and if there's more than 2 of you, probably a less expensive option. Very little is too far away. Get a Viagem card and zap it. You can control value better that way. There's plenty to do just taking in city sights, but if you have time, definitely go to Sintra and do as many of the castles as you can. I recommend a smaller tour if you want to go that route as they will use your time most efficiently. There's a lot to see. And if you like nature, get to Arrabida National Park for a kayak day trip. Water's cold but you won't regret it.
