Telmo and Diogo's communciations prior to arrival were timely. Digo was there to check us in when we arrived. The apartment was a studio-style apartment, clean and a nice comfy bed. apartment was super close to the National Palace and historic Sintra.
Only thing to note is that some Uber drivers may not be willing to pick you up/drop you off directly in front of apartment due to narrow streets, but the National palace is only a 3-5 min walk.
