I had a good experience letting a flat from Savills. Emily, my agent, was competent and was quick to understand my needs and wants for a rental. Unlike other agents she only took me to apartments that I was interested in. After a day viewing a few flats, Emily rang me that evening to let me know that a unit was just coming on the market and if I wanted to see it before anyone else. She thought I would be interested based on my previous feedback of the other flats she showed me. I was indeed interested and decided to take the unit. I mentioned to Emily that speed was a priority to me and she was able to get me through the application process and into the unit in less than 4 days(including the weekend). Their application fee was high(somewhere north of 200 quid), but the service was professional and Savills was quick to respond to emails/calls. Needless to say I will use them again.
