The house was great - three bathrooms and three double bedrooms, large lounge area. It's not a modern house, but lovely wooden floor and everything was right for us. April is not the best month for warm weather, but the log fireplace was great compensation. Small garden would be great in sunny weather.
Location is a quiet, residential area, but accessible for most things. Local supermarket 10 minutes walk has everything you'd need, train station and coast 5-10 minutes walk. We had no problems without a car - the Lisbon to Cascais rail line is great, and travel card system works across Lisbon trains and trams as well, very easy to load up and use, and good value. Uber also available. Only a few eating places in the area, but we mainly ate in the places we visited before we came back (Lisbon, Sintra).
If we come back to the area again, we will check out the availability of this again.
