The Week the Attic Rooms Became Unbookable
For about six days in early August the top floor rooms of the old centre stopped being usable in the evening, and the bookings moved downstairs and later.
Every summer produces one run of days where the building stock stops coping. This year it came in the first week of August, it lasted about six days, and the effect on bookings was sharper than the temperature alone would suggest.
Why the attic is the problem
An upper floor room under a roof has the smallest volume of air and the largest proportion of external surface of any room in a building. In February that makes it the coldest room in the house. In a hot week it makes it the hottest by a clear margin, and unlike the cold version there is often nothing to be done about it.
A roof that has been absorbing sun since nine in the morning continues radiating into the room until well after midnight. Opening the window at eight in the evening lets in air that is barely cooler than the air already there. Most of the old stock has no cooling at all, and the rooms that do have a unit frequently have one sized for a mild afternoon rather than for this.
What changed in the threads
Three things, all of them driven by guests rather than by the house.
Start times moved. The typical booking in that week began around eleven rather than around eight. The city cools noticeably once the brick stops radiating, and an eleven o'clock room in an attic is a different room from the same one at eight.
Lengths shortened. Two hours beginning late was written far more often than three beginning early. That is the sensible trade in heat and it was made without anyone suggesting it.
And the preparation advice inverted completely. In winter the instruction is to start heating when the hour is confirmed. In that week it was to shade the room from the early afternoon, keep it shut against the outside air while the outside air is hotter, and then open everything once the temperature crosses back.
What actually helps in an old room
Shade first. Curtains drawn against a sunlit window from midday do more than anything done at nine.
Move air rather than only cooling it. Humidity here is high, still air is the uncomfortable part, and a fan that circulates does more per euro than a unit that struggles.
More towels, four rather than two, because in heat they are doing the work that cooling is not there to do.
And lighter oil. Skin that is warm and slightly damp takes oil differently; a thin application does more than a generous one, and a generous one that would be right in January feels heavy in August.
What did not change
The arrival window stayed at forty to sixty minutes across the centre, because heat does not lengthen a short journey. The figures stayed where they are, with no summer loading and no winter one. And a room at a Schiphol airport hotel remained outside the window and arranged on its own terms, which in that particular week made it an unusually attractive option, since those rooms have modern cooling that a canal house cannot offer.
The honest recommendation
If you are staying high in an old building during a hot run, say so in the first message. It changes the suggested start time, the suggested length and the preparation advice, and all three of those matter more in that week than the choice of format does.
What the ground floor did instead
The mirror image is worth recording. Rooms low in a building, particularly those with a window onto a courtyard rather than a street, were the comfortable ones that week. Thick old walls take days to warm through, so in a six day run of heat the bottom of a canal house lags behind the top by a noticeable margin and stays that way.
The general point is that a building here is not one temperature. It is several, stacked, and the difference between the top and the bottom is larger in both directions than in modern construction. That is why the question in the first message is about the room rather than about the weather, and why the answer changes what gets suggested back.
Everyone in the room is twenty-one or over and what a session includes is decided by your therapist at the start of the visit. The heatwave page covers the whole hot week, and the oil guide explains why the season changes how an hour feels.
