We really enjoyed our stay here. We only saw Flora once, she wasn't there for or first two days, check in was easy; just read the check in manual online (I didn't). Her neighbors upstairs were friendly also; they come through the house to let the dogs run in the backyard.
Room was huge and clean, bed was comfy. Plenty of space to hang clothes. Private bathroom right next to the room was clean and looked brand new. Only problem with the bathroom was the steam from the shower doesn't leave through the fan very well, and the small window doesn't open, so best to leave the door open after to air out.
Whole house was beautiful, kitchen was big; but we didn't cook. She offers cereals/oats/teas and coffee for breakfast. Really nice touch.
Train is about a 5 min walk from the house, takes about 20-25 mins to get to Leister Square/Moorgate. Underground is easy to manage. Supermarket is also 5-10 mins away.
Overall for a much cheaper option than central London, and worth it.
