Hotel, Apartment or Hostel: Which One Actually Wins Your Trip?
A hotel is priced per room and a room sleeps two, an apartment is priced per flat with a cleaning fee charged once, and hostel beds are priced per person per night. Because the three grow in different directions, the cheapest one moves as your party grows and your stay gets longer. Put in the prices you are actually looking at and see which wins at every combination.
A two-axis grid over ten nights and six travellers, coloured by the cheapest option in every cell, with Berlin's 7.5 percent accommodation tax applied to all three and the crossover night computed for your party size.
The tool applies one fixed rule and leaves everything else to you. Berlin charges an accommodation tax of 7.5 percent of the net accommodation price on every paid bed in the city, hotels, hostels, guesthouses and holiday flats alike, with breakfast and other extras outside that base. That rule was read from the Berlin service portal on 5 September 2026. Everything else is your own numbers, because nightly rates move constantly and a guessed price would only tell you about my assumptions. Hotel rooms are counted at two people per room, so an odd-numbered party pays for half an empty room, which is often the single effect that decides the answer. The cleaning fee is treated as an extra charged once, which is why it dominates a two-night trip and disappears into a ten-night one.
What this tool does
It answers one question: for your party size and your number of nights, which of the three costs least. Enter the hotel room rate, the apartment nightly rate plus its cleaning fee, and the hostel bed rate, and the grid recolours to show the cheapest option in all sixty combinations at once. Your own trip is ringed. Underneath, the three totals are shown side by side, along with the number of nights at which the apartment overtakes the hotel rooms at your party size.
Why the answer moves
The three options grow in different directions. A hotel jumps in steps, because a room sleeps two and a third traveller needs a second room. An apartment barely notices party size but carries a one-off cleaning fee, so it is weak on short stays and strong on long ones. Hostel beds are the only option that scales with travellers and nights at the same time, which is why they win alone and often lose as a family of five. Read the grid left to right and you are watching the cleaning fee amortise; read it bottom to top and you are watching hotel rooms fill up.
The tax that applies to all three
Berlin's accommodation tax is 7.5 percent of the net accommodation price, and the Berlin service portal lists hotels, hostels, guesthouses, holiday flats, holiday houses and rooms in private homes as liable. Breakfast, the minibar, parking and similar extras sit outside the taxed amount. Business travel lost its exemption on 1 April 2024, and from 1 January 2026 the old ten-bed threshold that kept the smallest operators out of the tax was removed, so a two-room guesthouse now files the same as a chain hotel.
One thing to check before you pay for a flat
Berlin requires every whole-flat holiday listing to display a registration number issued by the district office, publicly visible in the advert. The Berlin Senate describes it as digits, letters and special characters, seventeen characters in total. Since EU Regulation 2024/1028 started applying on 20 May 2026, platforms also have to verify those numbers and report host data to a national digital entry point, so an unregistered Berlin listing is much more likely to be delisted between the day you book and the day you arrive. The host carries the fine. You carry the cancellation.
