We read some of the reviews on some of the websites about Cedar Estates before we used them, and bearing in mind some of the 1 star reviews we were a bit nervous. Luckily we haven't had a single issue with them. All the members of staff we've dealt with have been extremely helpful. Greg is a friendly and knowledgeable agent and Anne was excellent about answering questions and adjusting the date of our rental payments. Everyone we've met have tried and succeeded in helping us make the move from the Westcountry to London very easy.
I don't know if some of the poor reviews are real or not, but we'd recommend using Cedar and would definitely use them again.
