We've (me, my husband and my parents-in-law) stayed at Jonathans apartment for 5 nights. We've felt at home right from the start! The apartment is on the 15th floor and while it's next to a busy road, the noise never became bothersome inside: we could sleep really! Jonathan is really hospitable, having made sure there was already something to eat and drink in the fridge. The view is fantastic too, both during the day and night, you could look far into the distance, for example you could make out the Saint Paul's Cathedral, London Eye, even the Battersea Power Plant!
There are two bus stops real close, which made it really easy to travel to all parts of the city like Camden, Fleet Street, Saint Paul's, London Bridge and many more. The subway is just a bit further away, but we found travelling by bus the most scenic. There's a small supermarket just across the street, but we've also enjoyed one of the many takeaway restaurants who delivered our meals right to our doorstep.
All in all, we were all pleasantly surprised about the great price/quality which Jonathans apartment offers and when we would visit London again, we won't hesitate to stay with Jonathan again!
