Found. Put GK from Russia here, please return it to the homeland or to any cache from geocaching.su :) Thanks.

For sure it's not "small". Hint is useless. I was walking around the container maybe for 5 min before so realized that it's this. TB in

But where is the historic site???

Found, thanks. Tb in, tb out

Tftc

Wow, found GK I'm familiar with =) Took it again, let's move it somewhere more far away

Шустрик заселился в пещерке!

Шустрик покинул Хальштат и готов к новым приключениям!!!

Наконец-то Шустрик нашел место, куда приземлиться. Наблюдает за альпийскими красотами сверху

Great! Finished the series! Really liked it, all caches are pretty easy to find but at the same time many different hiding techniques. Thank you for all the caches!
The only sad thing is lack of English description, I suppose there should be some story for each cache which I missed due to speaking no German (yet?)
Dropped geocoin, took another trackable.

Ohh, the most long cache in Venice and, actually, looks like the only real multi (not simple one-step).
Regarding the stages:
0. As I said, please create waypoints, do nit write coordinates as plain text.

1. Coordinates are wrong. Correct coordinates N 45° 26.041 E 012° 20.343. On the given coords there is clock tower with only one bell. The view is nice from there, but you don't want to pay twice for two towers. And anyway, the answer can be googled easily.
2. I found some plaque with WWII soldiers listed, but number of people is wrong answer. No idea what the memorial is, but this doesnt really matter for final coords.
3. Ok.
4. Very difficult to find and also it seems it could be closed off-working hours. And "xs" is really not clear as for me. I would rephrase the question as "write down the year".
5. Wrong coordinates again. Spent 15 minutes walking around the gz, after that I gave up and went somewhere... where I noticed the figures! Correct coords N 45° 26.718 E 012° 19.920

6. Didn't find any graffity as well as steps. I suppose, coordinates are wrong again. I mean, I found some two-set stairs to the river near the gz, but the answer given results in completely wrong final point. So brute forced it to get point at cemetery island. The very first guess turned out to be correct point.
   Final. Actually I went there for another cache and had almost no hope to find this one. But I was lucky and my guess was perfectly correct. The only thing is that I have ni idea why is this musician "famous".. It's my very first time I see this name. No idea who is he.

   Dropped trackable.
   Thanks for the multi anyway, but it could be much more convenient if you fix the issues.
