It's a problem to rent a flat because there are many hotels in the town

Here are natural ways to express that idea in English, plus a few notes.

Natural corrections

• Renting a flat is difficult because there are many hotels in town.
• The abundance of hotels in town makes it hard to find a flat.
• There are so many hotels in town that renting a flat is difficult.

Notes

• “Renting a flat” or “to rent a flat” is more natural than “it’s a problem to rent a flat.”
• “In town” is a common, natural phrase; “in the town” is also okay, but a bit more formal.
• “Flat” is British; if you’re using American English, say “apartment.”

If you share your exam focus (British vs American English) or a sample prompt, I can tailor more practice or explanations.
