Is this email written correctly (I greatly appreciate your help in advance)

Thank you for your reply. I am glad to see that you remembered me during a Polish class. You were right, I was very busy with my job in Hotel. My job is mainly cleaning the rooms. As I have already told you it takes a lot of energy. I had a training for 2 days last week with someone who was working there for 6 years. We were cleaning 26 rooms per day then I was working by myself (15 rooms per day). We are supposed to clean 3 and half rooms per hour which is impossible for me. I am very very slow. But I don't blame myself since I am very new. Most of the people who are working there have been already working for 6 years. So I understand that it takes time getting used to it.

Thank you for your offer about meeting tomorrow after a class. Unfortunately, tomorrow I should work in a hotel from morning to probably 7 in the evening. I don't know about my next week schedule. Thus, if it is fine with you I will inform you as soon as I get the information from my manager. I didn't know still 3 sessions of our class is left. So, most probably I will meet you this week.
