We bought a house marketed by park & Bailey. We ended up looking for around 5 months before we eventually found our home. Park & Bailey were by far the most professional and helpful agents we viewed with (and we viewed about 25 properties in the end). The others required a lot of chasing, were hard to make bookings with and were very unhelpful with the offer process. Park & Bailey are the only ones in my view on par with central London agents, and as a purchaser, I would definitely consider them if you are selling!
