I stayed for 2.5 weeks - fantastic little condo which would be suitable for a lone traveler or couple.
Martin’s place is located conveniently to transportation (approx. 5-7 minutes walk to the nearest bus stop), it is about 15-20 mins walk from MRT station (Somerset, Dhoby Gaut) and very close proximity to cafes (like PS Cafe) and Robertson Quay.
It is in River Valley - which is an expat dominated area - it’s reasonably suburban but also close to the Central Business District too (for if you are working). There are some construction nearby and the condo is right next to road - so if you are a light sleeper - this may pose as an issue but it was not a massive issue for me.
The condo also has some good amenities - like saucepan, toaster etc. So if you want to make something simple for breakfast / lunch or dinner, you have the option to do so.
Overall, I really enjoyed my stay and would definitely consider staying at the same place when I visit Singapore again.
