Can't say enough about how charming the Watermill is. Very nicely renovated and equipped, and in a beautiful location. For us it was nice being in a remote spot. Ricardo does a great job as host, and clearly cares about making guests welcome.
One detail to note, just for full info, the cell service is weak at the Watermill, but fine at the top of the driveway, and there is no WiFi. For our trip, it was a very nice change to get off the grid, and there's a convenient cafe nearby if you really need to connect.
We also had a good time preparing a home-cooked meal one night. Especially welcome during a long road trip with lots of eating out.
No hesitation in recommending the Watermill for a very comfortable and interesting stay in the Sintra region. Thank you Ricardo.
