Translation of adhesion 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.
Sammy our cab driver brought us to the hotel, he promised to pick us up a few hours later. We took a shower and rested a little. I could not sleep because I was too excited of being in a new country.
Although we shared the ruins with about 3000 other tourists, it still left an amazing impression.
