I had to delay my arrival to Guillermo's apartment by a couple of days, and he was very accommodating of the change in arrangements.
When I met up with Guillermo and his wife, I was shown to the flat, which was as described. Just keep an eye out down the side lane - there are currently some leftover building materials, which you may not see if you're returning in the dark.
I was given a bowl of fruit and there was milk in the fridge, which was lovely to discover.
The neighbourhood too, is very community conscious, which I like!
A nice stay in a spacious flat, about 7 minutes walk from the tube station, and a 30 min ride into London central.
