Carlos and his wife are amazing and very kind people. They welcomed us very warmly and did everything to make us feel at home. The Apartment is located in Queluz city which is kind of in between Sintra and Lisbon. The train station to take you to Lisbon or to Sintra ( 2 opposite directions) is about 10 minutes walk from the apartment. The room is a good size, nicely decorated, with a queen bed that is suitable for 2 people, but the mattress is not firm (if you are concerned), big TV in front of bed and you can watch it while resting. The room is facing street and you can here car noises during the day but at night (12-7ish) is calm. I bet you don't want to stay indoor when traveling to Portugal. All in all we had a nice stay thanks to our wonderful hosts.
