Mumbai has the highest cost of living as well as the most expensive residential areas in India. And anyone who has even attempted renting out a place in Mumbai knows that it takes nothing less than diamonds to get a spacious one.
Travellers heading to Mumbai face a similar issue while booking hotels. Most hotels in the city are expensive and the budget options lack in terms of quality.
At one point, Japan had faced similar issues. But a decade ago, they introduced an entire market of pod-hotels. These hotels take very little space, accommodate upto two people in bigger pods and are a boon for budget or business travellers who need a place just to spend the night.
