The staff of WelkHome, which takes care of the rental, is indeed very kind. The apartment itself is very nice and clean, and has all facilities. However, during our stay the nights were very noisy, due to a musical festival, music from neighbouring bars, and people in the streets. So the 4 of us slept in the backroom, with earplugs and all windows closed (which made the nights also very warm). But we stil had good days in Cascais and this apartment.
