I have been with paramount for the past 12 years, they are excellent in all aspects, competetive, friendly efficient and honest. they have an excellent team, the maintenance service there is great, i never had to struggle or ask for something to be done more than once, they are very good especially in emergencies. You can count on their staff to deal with your queries quickly and efficiently. Paramount gives you peace of mind , so you dont have to worry about your rent or your flat. I would never think of leaving paramount, and from a personal experience and knowing many other estate agents, i think paramount are the best in London! would highly recommend!
