We have a lovely two bedroom modern flat in SW London, Battersea, close to local parks and apprx 20 min by bus from the center. We have two girls (3 year old and 7 months old), but there is also an extra bed so it could accomodate 1 more child. Plently of toys as you can imagine.
We are looking to swap for anywhere in the UK really, better if close to the seaside for 1 to 2 weeks from mid July to first week of August.
Let us know if anyone is interested, we can send pictures
