Located to portugal 4 years ago and when flying over london recently with my 10 year old realised she didn t reccognize any of the sights.So have booked us a flight for 4 days in oct half term to visit london. Hotels are SOOOOO expensive over there so thought about a house swap as we have done these very successfully in the summer. anyone interested? We have a 4 bed villa with pool and walking distance to beach near Viana do castelo, an hour above porto or an apartment near the beach actually in Porto and need a small place for 2 with quick and easy into the london attractions?
