Beautiful, pristine clean, light and airy apartment, with very comfortable beds (!), that I highly recommend. The view of the ocean is amazing and can be seen in full view from both the bedroom and the lounge. The apartment building is quiet, safe, and the neighbours are very friendly, respectful and always say "hello". I had long chats with people and everyone was very helpful. There is a small café directly behind the apartment, a 1 minute walk through the green gate, and a large coffee is only 1.50 euros! This is an authentic part of Estoril, not many tourists when we stayed there (July 2021) and a great place to mix with local people (which is exactly what we wanted). The apartment is also in a great location : only a few minutes walk from the train station that takes you all along the Lisbon coast to Cascais. Trains run every 15 minutes and until at least 1am so transport is never a problem. You can also walk into Estoril centre (around a 15 minute walk). The beach in Estoril centre is very clean, golden sands, and there is also a smaller beach around a 5 minute walk from the apartment which is just as lovely but smaller. The evening walk along the seafront between Estoril and Cascais is wonderful.
The apartment is a 3-4 minute walk from the nearest supermarket (Pingo Doce) which sells absolutely everything you need. Martim was very communicative and arranged for me and my daughter to be picked up by a couple of his friends on our arrival and which we really, really appreciated. And of course, the apartment is only around a 30 minute train ride to Lisbon centre (station Cais do Sodré, 1.85 euros) so Martim's apartment is a great base to explore Lisbon, the Lisbon coast, Sintra and Guincho beach, all of which I highly recommend. I would definitely contact Martim again to rent his apartment & thanks so much for such a lovely stay in Portugal, it was our first time and we loved it ! xx
