It was a very successful trip to Lisbon. The house is as every bit described and I think the 14 people we had stay was probably 2 people over what would comfortably sleep 5 couples comfortably together and with privacy. However each particular scenario would probably be different. We made it work. All I can recommend is to read carefully the different room descriptions and how the beds work. Also some
Bedrooms are only accessible through other rooms, also good to note. All the beds were very comfy, the kitchen was well equipped to cook meals, the views and windows were amazing, the location couldn't have been better. Our host was very responsive. There are only 2 keys so plan wisely for trips out where groups are split. All and all a great stay.
Thanks
