I prefer the second one - it has glass in the doors and other indications that it has not been updated as much, the bonus being original parquet in all rooms which if fabulous, the layout is better, bathroom much nicer, kitchen possibly not so much. I don't love the more recent parquet in the 3 bed one. But.. the 3 bed is on the ground floor .. which could be an advantage.
I LOVE 1930's properties and used to live in the area - this is a lovely part of the world. As for neighbours, there is a mix of people .. there are lots of flats and maisonettes, but equally, lots of large expensive houses and lots in between. I LOVED living in Hampton Wick.. lots of happy memories.
