I was on the market to find a new flat in North London. I was interested in a property marketed by Curtis Jones (Maria Valentino). I was really pleased by the way they have handled the process on behalf of the landlord: flat viewings at convenient times for me and never cancelled at the last minute (this does happen with non professional agents), 100% availability to go through the reference checking and support to get the best terms both for me as a tenant and the landlord.
I definitely recommend Maria and Curtis Jones if you are a tenant or a landlord. I will contact them again for any future property search.
