For short term might be yes. But for longer run, its not nice to stay. Coming from own experience (2 room around 700 sqft).

Now I've moved to a unit around 1k sqft so the difference between the spaces is much better. More storage space even for bigger items like luggages etc. If you are working from home then your 2nd room will probably be your work place too. But if you have 2 people working from home... then there might be an issue for both.

List price 445k-563k, guessstimate 356k-450k.
close to KTM, drivable to MRT/LRT so can work downtown KL conveniently.

But the thing is for resale wise better secure 2/3 carpark (purchased carpark) it as added advantage/ rental accessibility by walking to the train line need to be considered. If can see cannot walk over problem caused by train line, might be a bit tricky to take train (KTM might be close but the waiting time made a lot of people blacklisted it).
Visit the site on a rainy day to see if there is any water ponding issue.

690 is a bit small as compared to rumawip (build quality another story) but plan wise cooking will be mostly squeezed indoors rather than smoky frying activities being contained outside in the yard "wet kitchen".

Check lift to unit ratio. If I guess correctly 262 units. If 5 lifts anyhow (even 500u/block) isn't a big problem (20% capacity loss) if one is down for maintenance..but 3 lifts for 250 units, one down, 33% capacity loss and long wait time ensues.

Ahh then that is a good buy.
Since LRT from sentul not very far from Masjid Jamek there will be future demand.
5 lifts OK.
Try to get the extra carpark purchased. Will come in useful cos you and your partner will most likely have 2 cars. Also if not used can rent out.

seems good...
would be better if u can get the additional car park..
LRT nearby is plus point... even if u don't stay... rental sure good...
