Hello Surbiton! I need your wisdom and advice!

I'm thinking of buying a new flat in Surbiton. This week I've seen 2- a new build block of flats in Apha Road and also a converted flat in Ewell Road, just opposite the Fishponds Park. Both flats were really nice, so now I just need to think about the area. Today, I had a little wander around to get a feel for the area.

I wan't too sure about Alpha Road to be honest. The new build flat is lovely, but some of the nearby houses looked a little run down and scuffy to me. So that was a it disappointing.
