I spent six nights at Inge's.
The room was very nice and clean, as was the bathroom. You have your own key to leave and come back in and a second one to lock the room. Right next to the entrance is a wardrobe with a fridge and some cutlery and crockery, which was quite enough for the stay. There was even a socket adapter. If you have problems sleeping in brightness or noise (from the street), you should take a mask and earplugs. This made my sleep more restful.
The house is less than ten minutes away from the Tube with good connections to the city (District Line). It is barely five minutes from the house to small supermarkets and cafés.
I had a great time, although I would recommend everyone to take the Tube or bus more often if you want to see a lot. My feet didn't cooperate after the first two days.
Inge is a warm, friendly lady and I felt very comfortable and safe with her and in London as a solo traveller.
I will definitely come back!
