Well the flat is lovely has everything you need including a washing machine which was very useful, the area is nice and the binmen come at 1am every morning which is normal in Portugal and explains why the streets are so clean. Station is 5 minutes walk away and the beach 10 minutes.
Trains very regular takes 20-30 minutes to Lisbon, 10-20 to cascais. Get a card at the station machine and load it up with some euros and it's €1.31 a trip. There is also a beach ticket for 7 days for €12 but we used the metro so used the zap card. Shops, bars and restaurants within 10 minutes amble was the perfect base for our holiday. Host super quick to reply and very helpful as was her mum who met us at the flat. Only thing to say is Obrigado!
