Gitte's place was exactly what my wife and I needed for an extended stay, and she is a wonderful host! She has the room very clean and fitted with everything you need to feel at home, and she was really helpful whenever we needed anything else.
There is a bus stop right outside the front door, which made getting around really easy, and the Tooting Broadway underground station is just a 5 minute ride once you're on the bus (or a 10-15 minute walk if you prefer) for easy access to Central London in about 30 minutes on the Northern Line.
The area also has plenty of Food options nearby with the Tooting Broadway Market near the underground station, along with other local places to eat from all around the world.
We would highly recommend it!
