What a great little place!
The photos show it just as it is - a tiny "house" in a courtyard through a typical big Parisian doorway.
If you like super-sleek hotel rooms / apartments this may not be for you. However if you like somewhere with character, charm, and privacy, you will love this place.
There is no need to meet Gilian to get in, as access codes all work easily. However we did meet him, and he is charming and friendly.
