Singapore for week

Hi guys, 28yo female from the UK, I’ve had the opportunity to join a friend for around 1 week to Singapore before she goes on to do a 10 day tour in Bali, I’d be flying from the UK and transiting in Dubai (total journey 17 hours). As a fairly well traveled person, I’m finding it difficult to contemplate travelling all the way to Asia for what would end up being (with time difference) around 5 full days. My question for those of you who have been, would this trip seem worth it to you for the short time spent, or is in fact Singapore small enough to justify this length of trip? ☺️

Ps. My other option is Istanbul however it’s not as appealing to me because a) I’ve visited Turkey multiple times, b) I’m not sure it would suit my needs. However, any Istanbul advocates are welcome to give me points of interest (usually dining, nature and casually exploring) 🤗

TIA x
