>I've never stayed in a hotel room that large (neither in the US nor in Europe), more like 20sqm including the bathroom/shower. That's more or less correct, to give you a data point in Italy the minimum legal size for a hotel room (double, up to 3 star hotels) is 14 m^2 + 3 m^2 (minimum) for the bathroom, but usually they tend to be slightly larger. (the minimum becomes respectively 15+5 and 16+6 for 4 and 5 stars). For the single it is 8 or 9 m^2 (8 up to 3 stars, 9 for more) + the bathroom (again 3, 4 or 5 m^2 depending on stars). For 1 or 2 stars hotel it is not compulsory to have a bathroom "en suite", there must be as many bathrooms as (respectively) 40% or 80% of rooms. On the other hand, the very minimum size that you can legally call apartment (i.e. that has the "dignity" to be identified as "self standing") is 28 m^2 at national level, and a number of cities are increasing this minimum size (locally) to 35 or 40 (or even more).
