A story from my trip to Spain (part one)

Sevilla in August. If you don't know yet that this city is the hottest point place in Europe, you do know now! My friend and I used to spend the afternoons in a shopping mall where we had an air conditioning system and a restroom (in our travel dictionary the restroom equalled a socket, so we could feed our dead batteries in cell phones with the energy). We sightsaw [not a verb that is usually conjugated into the past; "we did (some) sightseeing..." would be normal] in the morning and in the mid-afternoon. Normally, we started our day at 9 am. Our bedroom was located on a beach. In fact, it was a small space covered with the sand. The pavement was alongside this beach so everybody could see us. However, it didn't matter, we managed to get used to it during months of being homeless. Nevertheless, in Sevilla we had a lot of adventures. Some were funny, the others - not necessarily. I'll focus on the bright sides. (two words)
I opened my heavy eyelids. What could wake me up so early?! I heard the reason before I saw it. The droning/whirring(? yes, whirring is fine!) of an engine was becoming  more and more annoying. Finally, when my visual acuity improved, I caught what the engine belonged to <--if you're looking to fluency, you should know this is not _strictly_ correct. A small yellow boat with two men on the board was about three metres from our sleeping bags. The men didn't pay even the slightest attention to us. They were from some kind of service because they were cleaning the beach. Although they didn't seem to be unfriendly, I woke up my friend and I told her that we should be going have gone. Like always, at the beginning she was honing complaining (honing is about sharpening a stick!) how stupid my behaviour was and how early in the morning I woke her up, but finally she packed her stuff up and we went to take a shower. Of course, we hadn't taken a real shower since almost three weeks. We had a bad luck with the Spanish hosts in on the south and there was no real beach with douches. So we used a wash-hand basin to wash our whole bodies. It didn't work very well, to be honest. I wanted to die because I could see how dirty my skin was. A dirt was so obstinate that the standard set (a soap plus water) failed trying to remove it. But not even so, a refreshing shower in the washbasin was still better than not washing ourselves at all...

Your english is pretty much fluent.  I've been strictly correct here, but hey, this is really good!
