Good choice.
Slovenia is a very pleasant country indeed. Beautiful scenery, Mediterranean climate, fine wines, very friendly people and interesting culture. A real up-and-coming vibe too.
Some observations I made whilst exploring the country:
It's a very hilly nation, and almost every hill seems to have a church on it.
Only four women in the whole country don't dye their hair orange.
Drink-driving in rural areas is rife, especially at night. When you visit a household, you'll have fine hospitality forced upon you; this will include copious quantities of alcohol (and much food), so if you're driving it really takes a politely assertive manner and strength of character to decline; insistence on consumption is, somewhat regrettably, the order of the day! Usually the roads are so quiet out in the sticks, drunk drivers often manage just to take themselves out, but be aware of the danger.
Slovenes (this is the preferred noun and adjective), like inhabitants of much of the former Yugoslavia, really don't like Albanians. Even educated and otherwise reasonable people won't hold back with expressing their detestation.
The fascinating architecture of capital city Ljubljana, and to a lesser extent the smaller cities of Celje, Maribor etc, is heavily influenced by the work of the renowned Plecnik, whose signature styles are evident almost everywhere you go, and very distinctive.
Almost all young people speak English very well - as with most European countries, it's the default second language. Among older people, the ability to speak it is significantly less widespread, and much of the older rural population speaks very little. In the cities, you'll have no communication problems. If you buy an English-Slovene dictionary in Slovenia, it will probably be very expensive (mine was £30 for a fairly compact one), so order one before you go if on a budget. Being a Slavic language, Slovene is not easy to learn; however, making an effort to communicate in the native tongue is definitely appreciated, so studying a phrasebook before going is highly recommended.
I wasn't cycling there, but I'd suggest it would be an ideal country to tour by bike....as long as you like hills!
