The place is really amazing! The photos show you how it is in real life. It is well-decorated, clean, and feels like home. It is also close to panoramic views and good restaurants.
The hosts are very approachable and helpful! They will even provide a whole page of recommendations for things to see and where to eat ;)
Do not hesitate to book this place. Just note that you need to hike up a bit to reach the place (but it's like this for most of Lisbon anyway). So, try to wear comfy shoes and try to pack light.
