Pretty much everything. On the plus side,
- Clean air
- Biking everywhere
- Sand volleyball on demand
- Cooler, drier temperatures
- Order
- A language I generally understand
- Great Chinese food
- Being the same time zone as my California friends
- My phone
- And Internet that works
But of course there are many things I miss,
- Ubiquitous art and architecture, and living in history
- Urban chaos
- Testaccio market and piazza
- Walking everywhere, in particular along the Tiber
- Italian food
- The music of the Italian language
- Minimalism and the simplicity of living out of two suitcases
- My Italian friends
