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. We were considering flying to the same region again: we thought of going to Brazil, Venezuela or Guatemala. We were asking a lot of friends on their travel experiences to these countries. My sister just moved to Boston, Massachusetts and I visited her for two days only. This means that I do not know the city but what i saw of it was really nice. I will visit her next month or so.
