We spent a lovely weekend at Flora's place. This is a very cosy home in a nice area and you will find anything you need, inside as well as outside (pubs, coffee shops, bakery, grocery etc...). The bus stop is literally 2min from the house and you can go pretty much everywhere quite quickly (Saint-Pancras is about 25min and Waterloo about 50min).
I strongly recommend this one ! Thank you very much Flora !
