We stayed in My Guesthouse 109 for five nights, paid c. €24 per night for a double bed, stayed in room 201 (faces the street on floor above ground level).
Location for us was perfect, just outside the core heritage area of Georgetown but still within a short enough walking distance to everything - e.g. 10mins walk to start of Little India, Chulia Street, 5mins walk to Limitations Bus Terminal).
Check in is stated as between 2pm - 5pm (the owner also will email you to remind of this). Given we were travelling from Koh Lipe in Thailand to Georgetown, we were travelling for c. 10 hours and knew we'd arrive late evening time. Thankfully the owner was accommodating of our late arrival (probably helped that we kept her updated throughout the day).
There is no manned reception however so be aware. She's available over email/whatsapp however.
Given the fact we had only arrived in Malaysia that day, we didn't have enough cash to pay for our accommodation up front - we had placed additional travel notes on our bank account the day prior to leaving Thailand but because our banks are slow to process this request, we technically have to let 24hrs elapse before we use the bank card.
When we asked if we could pay tomorrow morning, we were told there wouldn't be anyone around at all tomorrow and that we'd have to pay now. Luckily our card didn't blget blocked when the transaction was processed when we attempted it but it could easily have happened if our bank hadn't processed our travel note quicker than usual.
The accommodation is lovely itself, common areas (shared kitchenette, shared bathrooms, etc) are kept clean and tidy, we saw cleaners every day). There's a few cats that free roam around and a rabbit (in a hutch).
The room itself was large enough, high ceilinged, comes with small desk and chair, complimentary water (free refills from kitchen), doorless cupboard with coat hangers and wooden safe to store valuables (no lock was provided though), small bedside desk, decent AC unit (with fan only function also) small mirror and a few coat rungs.
In the five days we were there, our room was cleaned & towels replaced once.
As is advertised heavily around the entire properly, the walls separating the guestrooms are very thin and sound travels easily so even a normal volume conversation will be heard from next door. Didn't bother us too much, some guests that arrived in late weren't always very mindful of other guests but wasn't a big issue for us. Wi-Fi signal and speed were decent also.
Overall, would return to stay here given the great location, value for money and clean, tidy accommodation. Only suggestion to the owners would be to try have more of a presence in the property during daytime hours (if even only for a few hours).
