I stayed at Tania's place for 10 nights while on a trip to visit museums. It was quite comfortable for that length of stay as the room was very spacious, the linens quite cozy, and everyone there was concerned for my well-being. They ensured that I felt welcome and was well-fed, and the food was just amazing! The hospitality that each and everyone showed me was incredible, and I easily grew fond of everyone. It is a very welcoming place!
The location is perfect. Walkable to many great places such as Kensington Gardens, Hyde Park, the Natural History Museum, Science Museum, Victoria and Albert Museum and Royal Albert Hall, it is in a safe neighborhood. It is short walk to the Gloucester Tube, making all of London and beyond accessible.
There are several good restaurants nearby, a few shops, and the place is walkable to Kensington High St. with more than enough shopping for most people.
I would stay there again in a heartbeat (and hope I do!). Visitors should be aware that there are stairs (they kindly tended to getting my luggage up and downstairs). I did not find this difficult, but someone might. Also, being that the windows face the street, there is street noise. I would recommend bringing earplugs.
Tania communicates well and responds quickly to inquiries and there were no surprises concerning the transaction of the stay. You can feel assured that they are upfront and follow through.
