+  header: Sizes and kinds
+  text: We offer different sizes and different types of studios for artists. There
+    large and small rooms, with more or less light, also rooms with tiles for wet-work.
+    The rooms are in the old hospital wings, so most are old patient rooms, but there
+    are plenty of others too. Prices do not include electricity or vat, but do include
+    the use of common spaces, see below.

+  - header: Standard
+    text: This is the standard 2 patient room. They are mostly towards the south,
+      so may have great, or too much light, depending on how you see it. The size
+      is about 3x5, cost 120e.
