Well, Hilda is a busy busy English lady loving flowers and gardening.
She has her rules and the touch of a grumpy Englishness that you might have seen or heard.
The negatives were:
Shared toilet and bathrooom, as we were 4 people with 1 toilet and 1 bathroom.
If you are a family type and on a holiday, aiming ar exploring London and feeling the atmosphere of a typical quiet working class suburb, that might be just fine.
Hilda has her own ways and rules nevertheless some charisma is lurking in them
On the strong positive side:
Excellent location for travelling around London: 300m from a train and tube station (Luton, Gatwick, Heathrow arrivals), supermarkets, groceries and shops within this 300m reach, quiet and clean neighborhood.
Hilda's expertise on routes and sightseeing and general knowledge of London and how to get here and there in an effcient way, what and when to see.
Basketball field just next to the apart, and lots, lots of flowers and artefacts and plants on Hilda's.
