A Capela was amazing! The place was sparkling clean upon arrival. The chapel and all of the grounds are picturesque. Felipe our host was waiting upon arrival helping us into our private parking space and then showing us around the place. Additionally, we were greeted by a bottle of wine as a house warming gift. The location walking distance to Sintra downtown ensures this place checks all of the boxes. This place is a home run if you are looking to explore Sintra.
Pro tips: the parking spot is located past A Capela which can be confusing on the map (and with Waze) and if you miss it, you will have to drive back around town. If you are limited on time, you can take an Uber to the front gate of Pena Palace and back down the mountain which saves a couple of hours. And be sure you buy a ticket for the first tour to avoid the crowds.
