Elisabetta is so lovely! You will absolutely love her and her beautiful home. The house is very clean and it is easy to get to get around London with Lambeth North and Vauxhall stations 10-15 minutes walk away (depending on your speed of walking). It is also very easy to walk across to Westminister where the Houses of Parliament, Ben Ben etc are. Maybe 15 - 20 minute walk.
The house itself is very clean, and I do agree that the bed is super comfy! It's quiet at night time so you can get a good sleep, and plenty of cupboard space to hang your clothes.
Elisabetta is very helpful, giving many tips of things to do and see in London, as well as the best ways to get there. Her recommendations are spot on and I enjoyed myself in London very much.
I have no hesitation in recommending her place to anyone!
