We really enjoyed staying at Hannah's flat.
The flat is big and cosy, very clean and the bed is comfortable. The kitchen is also big and you have everything you need to cook.
The flat is 10 minutes walk from Oval station so you can easily get to the center and there is a Tesco nearby open til late.
We didn't meet Hannah in person but she sent us all the information we needed about the flat and we found that the self check in and out was very convenient.
