I really enjoyed my time in this studio, which is very centrally located in the historic district. There are tons of dining and shopping options and it is extremely close to Quinta da Regaleira and another Palace. Castelo dos Mouros and Palacio da Pena are further up, but I hiked up just fine, or you can hop on a commuter bus for like 5 euros.
When I arrived everything was spotless and laid out, including fruit, cookies and water. Izumi's husband was so nice and showed me around when I arrived and their puppy gave me a nice warm welcome as well :-)
I disagree about someone else's review about the noise. For a family with two dogs and a little boy, they are extremely quiet. Also, they do have the room listed as a private room, not whole apartment, so it's not like monastic silence was advertised. I thought overall the studio was incredibly relaxing and peaceful, with good views, cozy bed and access to the awesome garden.
