Nice room, lots of privacy and large enough to spend some time inside if you don't want to go out.
Ola rents out two rooms, we had the 2-3 people room.
She has been doing this for a while and she gets you settled right away. Ola has a warm and open personality, yet gave us lots of privacy. She made us feel very welcome. We didn't rent a room from her, we stayed in her home.
The bed was a pop-up bed but it slept so great, we actually slept better than we did at home. (jealous). The curtains are remarkably dark so if sleeping late works well.
You can prepare and eat your own food in Ola's very well equipped and very large kitchen (jealous again). But if you want to take it easy, I'd recommend calling for Indian food. Or walk to the Chinese on the corner. Or the Thai.
There is a local pub (for local people) in walking distance and another one a little further (at Waddon station).
Public transport is good, easy and frequent, but you need to get your tickets in advance - so get an Oyster card or buy paper tickets at Waddon or Croydon West.
The room is a full 30 minutes from London center and public transport costs 12 pounds per person, you may need to take that into account. Google maps works well (wifi !) and it can for the London public transport system.
We stayed five nights in all and we had a lovely time.
