A comfortable place in a very convenient location. Though it's not especially Portuguese, we enjoyed the Bengal Tandoori Restaurant - especially the kids who were not enamoured of Portuguese cooking.
Parking was difficult. I ended up parking wedged up against a wall in a narrow alley called Rua Murtas, uphill from the apartment. You don't need a car to get to any of the sights. Next time, I'd take the train.
Take a tuk-tuk or Uber up the hill to Pena early to beat the lines. The ticket vending machines at the entrance seem to be constantly breaking down. The entrance to the Moorish castle is a short walk from there and the walk down along a wooded trail and past the rock-climbing wall is really pleasant and not too strenuous. Don't miss the Poço Iniciático / Quinta da Regaleira. Walking down the spiral staircase into the well is magical and the caves are very cool, in all senses. That was the kids' favorite. The Palácio de Monserrate is a little further out, but well worth the side-trip. With the best gardens of the lot, it's a great spot for a picnic.
