Phil's guesthouse is big - much bigger than it looks in the photos! The main room (I didn't measure it) must be at least 60 or 70m2 - and then there are two good sized bedrooms, a big bathroom with walk-in shower and extra space in the garage for storage and laundry. It's also super clean, modern, and stylishly furnished with good quality fittings and appliances. The fridge even has Wifi! The guesthouse itself is completely separate from the main house, with its own outdoor sitting area and loads of parking, so there's plenty of privacy and no sense of being cramped in or treading on your host's space. Phil and his partner were there to welcome us and were super friendly, helpful and responsive during our stay, even leaving us a bottle of wine for our first evening. if you have a car the location is convenient with everything you need in easy reach; if you are on foot then there are supermarkets about 10-15 minutes walk and you can take one of the frequent (and cheap) trains from Merces station (about 35 minutes walk) into Lisbon or Sintra. We were here a week and would have been perfectly happy to stay considerably longer - highly recommended!
