A break to the Big Smoke or the City That Never Sleeps is high on many travellers' wish lists.
However, a break in the wrong city can leave visitors' nerves shredded and less well rested than when they left.
To help travellers plan a city break on which they can truly unwind Zipjet has compiled a list of 150 of the most and least stressed-out cities in the world.
Travel meccas such as Paris, 78, come way down the table for peace and calm.
The Baroque European hub of Brussels comes in way down the table at number 120, on account of its terrible employment prospects and mental health scores.
The approach of London-based dry cleaner to the jet set is surprisingly methodical.
Ranking cities from 1 the best to 10 the worst for criteria including debt per capita, access to green spaces and pollution the company created a ranking of 150 cities around the world.
And the conclusion? We should all relax and learn German. Half of the top ten places were Teutonic strongholds against angst, and a remarkable seven of which are German-speaking cities including Austria's Graz, Luxembourg and the Swiss city of Bern.
However the car-producing city of Stuttgart in Baden-Württemberg is the world capital of chill. In spite of being the home of Mercedes-Benz and Porsche the city enjoys almost perfect air quality and one of the largest areas of green space in Europe, both of which were big factors in claiming the top spot as 'most relaxed city'.
Perhaps we should all be planning a holiday to the Deutschosphere.
Or you could just stay put. Kiwi calm and pure "she'll be right" attitude has landed Wellington in place 13 and Auckland at 15 for most relaxed cities.
The least relaxed cities? Kabul at 149 and Baghdad at bottom most, although the Iraqi capital did come in the top 10 for light quality.
