Need recommendation for Stays in Lankawi and Kuala Lampur for a family group

I wanted to reach out for recommendations. My family and I are planning a trip to Langkawi from 10th June to 13th June and in Kuala Lampur from 13th June to 16th June

Our group consists of 8 adults and 3 children:

• 4 senior citizens (above 60 years)
• 4 adults aged between 30–40 years
• 2 children aged 10 years
• 1 child around 2.5 years old

We would ideally need a property with at least 5–6 rooms. Since we are traveling with both children and elderly family members, having a kitchen would be very important for us.

We would also prefer accommodations located closer to the city, with easy access to restaurants and supermarkets.

Could you please recommend suitable properties that would work well for our group? Looking for budget friendly recommendations since we will be in the room only to crash and to cook food.
