Can anybody correct this text?

Vienna, July 8, 2015

Dear Catherine,
How are you? How is your vacation going? Are you having the time of your life? I hope so. My vacation has just begun! I left Rome two days ago, and now I'm relaxing on a soft bed in a small, beautiful hotel in the center of Vienna.

To be honest, the beginning of my vacation was a disaster! The forces of evil seemed to loom over me, and they appeared to want me not to go on vacation. First I forgot to set the alarm clock for 7AM, and I woke up about a half hour late the next morning. I caught the train by the skin of my teeth!
Once I arrived in Vienna, I realized I had left one of my two suitcases at the station...in Italy!
When I finally got to the hotel, the receptionist told me they hadn't received my email, so I didn't have a room! But they told me that if I had the patience to wait a few hours, they'd have a small room for me. 
The owner of the hotel apologized for the situation; they are really polite and remarkably sorry for what had happened.

However, I had time to kill so I went to a cafe (great place) and ordered a local beverage. It tasted awful at first, but when I swallowed it, it tasted really sweet.

As it was raining and I didn't have an umbrella, I decided to stay there. I took out a book and my *MP3 player. You can't imagine how relaxing it was: reading while listening to Beethoven's Sixth Symphony, sipping a warm drink, and watching the rain.

As far as the room I'm staying in, I couldn't be happier with it! It's like a little bit of paradise in the center of the ancient **Imperial city of Vienna. Last night when I was lying in bed, I imagined that all the people in this hotel are ***its angels. I'm sure you'd be laughing at me if you were here! "You have an over-active imagination," you'd say as always. Maybe you're right, but one thing is certain: this place is heavenly! You should have come. Vienna is such a lovely city. You'd fall in love with it.

Tell me what you're up to! Looking forward to hearing from you,

Cristina

Ciao Cristina. Il tuo inglese è veramente ottimo. Tre domandi e un suggerimento. 1) *Nel suo testo, scrivi “switched on the MP3.“ Sente strano in inglese perché ora nessuno parla di MP3. Ognuno ha iPhone, iPod etc. Potresti dire “put in my headphones.“ 2) Non capisco che vuole dire “Imperial City of Vienna.“ A me, sembra strano. 3) Gli angeli - Sono gli angeli dell’albergo o della città? Non è claro qui.

Infine, questo è giusto la mia opinione, ma penso che tu usi troppi punti esclamativi!!!!! ;) Spero che tu capisca il mio italiano, non è così buono come il tuo inglese.
