Super clean, well located, coded doors, which is helful since the flat can host 6people, so no need to share keys. There were church bells ringing in the morning, but considering the size of Sintra I dont know if anything different is possible! Maria's office is just round the corner, which is helpful, to drop the stuff on the check out day, or if you need anything (we've requested irening board and got it in less than 20min!). A good stay overall
