The apartment is modern and clean and the location can't be beat--easy walking distance to all the sites and close to public transportation if you want to visit Sintra or the beach. We had some great meals at the restaurant (Maria Cantita) located on the ground floor of the building.
Communication with Rita and Laura was great. At check in, Laura went over everything in the apartment and explained how to use the public transportation system. Laura recommended several sites to see and there was a binder with more tips of places to go and to eat.
Only downside of the apartment is it is on the top floor of a building without an elevator. The stairs weren't a problem for us (and a good way to work off all the pastries!) but would definitely be an issue if someone in the group was mobility impaired.
