Flagstone have been fantastic throughout our moving process. A particularly special mention for David Marsello, who has been an absolute pleasure to deal with from the start. Not only has David been super quick and easily contactable, no matter the query, he is a true gent as well and has been an ever friendly and helpful voice during, what for most, can be a very stressful time. There have been a number of rate changes since our initial meeting, and David is always on top of this, and always looking for the best deal for us.
If you are based in the Essex area, I cannot recommend David, and the Flagstone team enough.
