Mário is an excellent host, well deserving of his super host status. He's friendly, laid back, and his communications are prompt. He's also very thoughtful as he provides personalized touches for his guests that really makes them feel welcome. Regarding the apartment, it was immaculately clean, and Mário provides weekly cleanings for long term stays. The apartment has everything needed for a comfortable stay and the location is convenient (walking distance, or Uber for those that don't do walking) to pretty much everything in Cascais. There's only two things I can think one might want to be aware of when staying here, and they aren't really big issues. The first is that on Sundays, there seems to be a community church in the basement unit (under Mário's unit) and they really like to start singing around 10-11am, so if you want to sleep in on Sundays, bring some earplugs. There's no loud noise at any other times of the week though, so this wasn't really an issue for me. The second thing is that the hot water only lasts between 5-10 minutes depending on how you use it, so if you are the type that likes to take long hot showers, this could be an issue, but considering it's summertime and hot outside, this also wasn't a big issue. Other than those things, everything was perfect, clean, and comfortable, and I'd highly recommend a stay here for those traveling to Cascais.
