This appartment is perfectly located close to public transportations (BARBICAN Station) and near Saint Paul's Cathedral, very clean, well equipped. You have a supermarket on the ground floor (it's good point!). Didn't met Vishnia but Vishnia's friend (named Martin) was sympathic and discussion with Vishnia was good & clear :-). Very convenient for 4 guests. I'll recommend this appartment.
ALL WAS FINE!
