Translation of rob in Spanish

I guess you know Spanish very well. I'm not on line most of the time. I think to get accommodation in the city is hard. I have many friends in Madrid, they all live outside the city. I think we can help each other to practice German or Spanish.
Thank you for your kind mail. I guess that we are friends now! The last winter was extremely cold. Now in Summer the weather is nice. My English is terrible but i hope that you will give me a chance.
I think I have to switch back to English. It will take me two years until I write an entire letter in German and I suppose I do not have the time for it. Does that mean that I am not serious about learning?
