Vanessa responded very quickly to my message and was here to hand over the keys. I found the flat very clean and spacious.
There's a very comfortable futon bed with a very good duvet, excellent cooking facilities, enough space to eat comfortably and a practical shower room. It's tastefully furnished and really got a homely feeling.
It's very well situated (bus, tube, shops within 5 min walk). The area is quiet in the evening.
Negatives: the entrance is at the back of a building and is reached through a small alley, one could feel a bit insecure coming back late in the evening. I found the heating fan noisy and turned it off during the night. And there are major building works going on all around, excavating and drilling starting at 6.30. Given the size of the excavation, I'd say the works will go on for at least a year. So no lie-in in the morning. It was fine for me as I was here for work.
I would definitely come back, once the building works are finished!
Thanks to Vanessa and Chris.
