I'd say No. How many stars does the hotel have?

Each hotel may have its own rules, the one in Germany last weeked did mention that using your own equipement to heat food or drinks was not allowed due to fire risks. Best stay in a hostel where you have the use of a kitchen. They often have double or family rooms.

Most hotels do not want people cooking in the rooms, for both safety and smell. Guests don't want to check into a room that smells of stale cigarettes or stale bacon grease.

You'd have to ask the hotel to be sure, but hotel fire safety is a huge issue (even without a flame) as hotel fires can be incredibly deadly, so it is often not allowed. You're best off trying to find an extended stay hotel that offers some type of kitchen facility (or a hostel where a shared kitchen is available for all guests). Some hotels can arrange a microwave for you, if that helps.

of course the answer is "no" on this one. you can't cook in hotel rooms.

That's not strictly true, as some extended stay hotel chains will have kitchens built in which you may use for cooking -- and I'm sure they have appropriate fire protections to allow that. But yeah, bringing your own stove to a hotel room not designed for it is a problem.

I'm kind of surprised about these comments. I've in in dozens of hotel rooms that have a microwave. How different is that from a small electric stove?

@ZachLipton: What about, like, an electric pressure cooker? I don't imagine it'd have a higher risk of fire than, like, a hair dryer or iron or something like that...

@MartinArgerami One is fire risk, which for the UK especially will be a big deal. The other is that those rooms with microwaves have put them in expecting you to use them and make smells. Hotel rooms without them won't.

@martin_agerami it's far harder to start a fire with a microwave than an open cooker, and I suspect they are safety-rated to contain the fire even if it's possible to ignite (say) a potato by microwaving it for a whole hour. (I have never tried). I would not ever want to stay on the 15th floor of a hotel that allowed guests to do shallow-fat frying in bedrooms below me. I very much hope that the room fire alarms would trigger well before the bacon actually caught fire, and that the errant guest would be heavily fined or prosecuted by the fire brigade.

@MartinArgerami: "I've [been] in dozens of hotel rooms that have a microwave" In the UK? Really?

@LightnessRacesinOrbit: no, not in the UK. Neither the comments nor the answers address something particular about the UK, as far as I can tell.

@MartinArgerami: The question is about Glasgow, which is a city in Scotland.

Get a hotel where it's build in: For example glasgow.frasershospitality.com/en/accommodation.html

@MartinArgerami: The microwaves in the room have probably been checked and admitted by someone in the hotel who is responsible to check fire safety. A random guest's portable stove has not. That is all the difference that needs to be there for the hotel to allow one and prohibit the other.

@Hilmar Haha I posted a link to that exact place on one of the answers. It was extremely easy to locate several hotels in Glasgow that offer kitchenettes. And they're surprisingly cheap too.

Airbnb is the answer you are looking for.

Most Israeli hotels have a small kitchenette in the rooms for cooking. This would include a small sink, a large mini-fridge, and enough platterware for a family of five or six. Perhaps the OP would be better off holidaying here!

Glasgow does have plenty of great restaurants, BTW. :)
