The value for Tiago's apartment is spot on!
We had the place to ourselves and loved it.
Your 25 min from the Old DT center and 25 min the other direction from the castles in Sintra. You have a supermarket across the street and a very inexpensive cafe by the front door of the apartment.
Bathroom was clean, shower water pressure and temperatures were excellent!
Note: the bus stop and very busy street are below you... if you love the big city white noise - prepare to be lulled to sleep 😁.
