Margarida's place was just perfect for the two weeks I was in Portugal. My daughter is now living in Monte Estoril and I visited her over the 2018 Easter holidays. Margarida's apartment was a great nearby location for me. The apartment was very, very clean and tidy. All of my basic needs were met. There isn't an oven but there is a microwave and hot plate for cooking along with plenty of dishes, etc. Margarida has set up a nice little tea and coffee area for her renters, too. The bed I slept in was quite comfortable. The apartment is located in a lovely residential area but not far from restaurants, shops and other attractions in Monte Estoril and Cascais. There is a well stocked and modern grocery store (SPAR) that is only a minutes walk from the apartment. This was very handy. I was traveling alone and I felt very safe in this location. The train station is about a fifteen minute walk and trains regularly go into Lisbon from this station. It is roughly a 25 minute trip from Monte Estoril to Lisbon.
If you're looking for a pleasant location to perch while you're visiting Portugal, I'd definitely recommend Margarida's place.
