Translation of musaraña

I learned Russian during 8 years in highschool, but since I left school 6 years ago, I have forgotten most of it and did not have opportunity to speak or practice in any way. That's why I am on Vocabulix.
I think it's a good idea to fly to Antigua to a language school. I feel more confident with the grammar in Spanish. Perhaps it would be better if the school would arrange the accommodation.
I'm helping you with Spanish and you can help me with English. How did you teach yourself the grammar? Here in Zurich it has being raining for 5 days and we have spent most of the time in front of the TV.
