Eddie's place was fantastic, and everything we could've hoped for when staying in another country: safe, close to public transportation, easy access day or night, a lovely host (Eddie was away during our trip, but his housekeeper, Susan, was a joy), and a fantastic representation of local cultures all under one roof.
Some tips from an American traveler staying in Singapore:
1) The MRT system is all you'll need to get around this beautiful city-state. Although it's possible to walk to the nearest MRT station from Eddie's place (takes about 15 minutes), we found it most convenient to snag an Uber/Grab. This costs between $6-$12 per trip from the house to the station, depending on the time of day. Once you're at the MRT station, talk to the employees behind the glass booth and snag yourself a preloaded MRT card, as the card will need to be swiped every time you get on and off the MRT at various stations around the city.
2) It can be both cheap and expensive to eat in Singapore. If you want to stay on the cheaper side and experience what Singapore is known for, visit as many of the "hawker centers" scattered around the city as you can. Think of these as massive food courts, some with up to a hundred vendors, selling a variety of delicious genres of food FOR CHEAP (we're talkin', like, $3 per person cheap). Chicken & Rice is Singapore's "national dish," so look out for that at every hawker center. Hit up Google or YouTube for the best spots to eat.
3) Bring cash! Although quite a few restaurants will accept your out-of-country VISA card, every hawker center we visited was cash-only. There are ATM's scattered around the city, and always at MRT stations.
4) If you're looking for souvenirs, the place you need to visit is CHINATOWN (and again, bring cash). Seriously, don't buy anything from touristy spots like Gardens by the Bay, the Singapore Flyer, Marina Bay Promenade, etc unless you want your wallet to get hosed. Chinatown is packed to the brim with vendors selling super cheap Singapore souvenirs, clothes, toys/plushies, decorative items, jewelry, and more. We often found the exact same items in Chinatown that we saw at Gardens by the Bay, for example, for a fraction of the cost.
5) It's hot and humid in Singapore, so pack accordingly (including lots of water). Maybe bring one or two nicer outfits for fancier outings, but for our week-and-a-half stay, I was almost always rockin' shorts and a t-shirt. Also, be prepared for the occasional sprinkle. Rain in Singapore is random but quick, and never seems to stick around long.
6) There's quite a bit to do for entirely free, so hit up Google and find a list of sights to see without spending a dime!
