I absolutely loved everything. The house is super comfy and charming. It has everything you need. The sheets and duvets smells so clean as no-one has ever use. The house is super clean. There is a dehumidifier in the house (it may be better to turn on and leave it on while you re out, it will help against the humidity). I loved it and highly recommend it! Vera responded promptly to everything I needed. Flawless.
The last point I would hightly consider is that Sintra is definitely not a city to stay for too long with an infant under 9 months. The humidity can be tough for their respiratory system.
