The location was good for us, walkable to a wedding and other places to eat. If you don't like walking, you'll need Uber/Bolt to city center of Sintra and other major attractions. It's a 25 minute walk to city center and palace of pena is not walkable. Nice building, well kept. It was clean. But we searched specifically for air conditioning, which was our top criteria. We like to sleep at 69F (20.5C). When we arrived we found there was no air conditioning. It is the unforgivable sin. Very hard to sleep. Thankfully it was not hot the week we were there, but there were not enough windows to get good airflow, plus keeping windows open leads to a lot of street noise, especially on Saturday night with nearby bar.
