Maria's apartment is great. We stayed for 5 nights but it was not long enough. It is quite spacious for a studio and is perfectly located in the heart of Cascais, close enough to be at the beach or one of the many nearby cafes and restaurants within a couple of minutes walk, but far enough from the noisy part of town.
Maria was a very helpful and responsive host and provided some really good recommendations on where to eat, we tried them all and they were excellent, one of the restaurants (sushi) is literally behind her building and was a good choice. The street was generally quiet, the upstairs neighbour did make some noise at times but this was not a major issue. The bed was comfortable and the shower was powerful. We hope to come back to Cascais soon and would love to stay in Maria's apartment again, thanks for having us.
