Everyone has a Paris that they fantasise about. Some dream of dining in candlelit bistros, others hanker after markets heaving with cheeses and warm baguettes, perhaps you imagine getting lost in a maze of old streets, stumbling upon delicious patisseries and hidden courtyards.

The sad truth is that whatever your particular Paris fantasy is, it's hard to find in reality. The City of Lights is a big and busy capital: tourists swarm, noses in guidebooks, from The Louvre to the Musée d'Orsay to the Eiffel Tower to the Champs Elysees to Montmartre. Getting off the beaten track is no mean feat. Many of the city's rarest treats are almost impossible to find, eluding even the most avid of guidebook writers behind unassuming doors.

So, what if for €175, less than the cost of a pair of Parisian Louboutins, you could find your fantasy? Richard Nahem, a native New Yorker, has been living in Paris for three years with one mission: to show people the city he loves and the one that tourists seldom see. From the moment he made the move to France he was inundated with requests from friends and acquaintances to show people the "real" Paris and now he's made a business of it, Eye Prefer Paris Tours, which dovetails with the places that he features on his blog Eye Prefer Paris.

Richard's tours cater to a maximum of 6ish people so you're guaranteed a personalised experience. Based on clients' interests tours take a specific theme – e.g. shopping, markets and gourmet food, architecture and culture. Standard tours (€175) last three hours, those looking for more can extend to a full day, three days or a week if needs be.

Most tours centre on the Marais district, Richard's home and area of expertise, which spreads across the third and fourth arrondissements. Le Marais is one of Paris's most impressive areas, packed with 16th and 17th century private mansions, secret courtyards, neighbourhood restaurants, outstanding patisseries and traditional ateliers. Unless you know where they are however they all too easy to miss, chances are you'll be swallowed up instead by the tourists who flock to the district's famous gay bars and kosher restaurants.

Richard describes the perfect three hours in Paris as exploring the Place des Vosges (the oldest square in the city, dating back to 1605); stopping for a coffee and a pastry at one of the best patisseries in town; visiting a chocolate shop where you can buy all the chocolate sculptures you could ever dream of; uncovering a secret garden where wild roses grow unchecked; soaking up impressive 16th and 17th century architecture and exploring former private mansions.

Food lovers can look forward to Paris's Bastille food market (the city's biggest), gourmet food shops and the inside scoop on where to eat. Die-hard shoppers will feel lightheaded at the prospect of speciality shops, exclusive to Paris, where you can pick up organic cosmetics, stashes of handcrafted jewellery, piles of pashminas and Parisian couture. Culture vultures can sate themselves on Richard's expert knowledge of the history behind the city's streets, buildings and gardens.

As Richard puts it, "I'm here to fulfil peoples' Paris fantasy" - everyone dreams about Paris and whether your version includes ateliers and authentic restaurants or palaces and patisseries, Richard's goal is to find you exactly what you've been looking for.
