Ray has a very nice place in the heart of London. It is easily accessible to 2 tube stations and in a nice neighborhood. Ray was a great host who went out of his way to make us feel comfortable. He greeted us when we got there, helped us with our luggage and left mugs and tea in our room. We abruptly had to cancel our trip and Ray was generous enough to give us a partial refund.
I think it is a great value for the price, but since it is not the nicest airbnb I have to give it 4 stars. You get what you are paying for. The place is very affordable but this also means that the room is quite small for 2 people and you are sharing a bathroom often with other guests who take the other room. By the way, all of this is upfront on the listing so it was not a surprise.
Overall we thought Ray was a great host but probably would splurge on a nicer airbnb if we are staying in London again!
