Michael's place is a terrific location - around the corner from an Underground line that goes straight into the heart of London, and 2-3 minutes' walk from a couple of supermarkets plus other restaurants & shops. You definitely get more space for money than staying farther in the middle of town and yet still have easy access. I only communicated with Michael electronically but he was always easy to reach, and his property manager was terrifically friendly and helpful.
This is London, so the place is not huge, especially if you are two travelers rather than one. However, there is ample closet and shelf space for putting things away, and everything in the kitchen worked well. For elderly travelers or anyone else with bad knees, I would caution that the stairs are a bit narrow and steep for getting luggage up and down, but again it's nothing out of the ordinary for London flats. There's occasionally a bit of street noise from the neighborhood but nothing that ever disturbed my sleep. And Finsbury Park is huge and only a 5-minute walk away if you ever want greenery. Overall this is good value in a very convenient location -- thanks, Michael!
