We loved our time at Petra's house! Everything suited us (group of six: grandparents, parents and two children). Stairs to kids room are steep but absolutely fine for our kids (5 and 8). And the kids loved the backyard and trampoline after a day of exploring London.
House is so close to train station and then only short trip to city: so easy to go everywhere.
Petra has everything very organised, and we felt that every support was available. Thank you Petra and her lovely family for sharing their home. We definitely recommend.
