Nothing hatches in my living room, there is a spawn point down the road but it is inaccessible from the public highway as it is down a private drive. If I get enough GPS drift I can occasionally hit it from the top of my garden.
I was in London yesterday... what a revelation! It was non stop pokemon catching with loads of cubone, marowak, gastly, haunter, gengar, meowth. I got particularly excited by catching 3 dratini (dragonair ran away), magmar and enough magicarp to stack up 300 candies. My bag is full from all the pokestops and one of my 5k eggs hatched a Tangela. It was pokemon heaven.
I'm walking a Graveler and now on 76 candies, when he is done I'll swop to a Dratini.
