Inexpensive, and you get what you pay for

I booked three rooms at the Sheraton Mustika in late January - it was inexpensive, Starwood, and located in Yogyakarta (the exact qualities that I was looking for). While the facilities were dated, it seemed fairly reasonable for the price (around US$60-80 per room a night).

Check-in on the 7th floor went smoothly (or so I thought). I was not offered any upgrades, but decided not to press for one. I was asked if I wanted to keep separate folios for each room - initially I said this would not be necessary, but requested it after the front desk agent advised me that at times the stay/room credits did not accrue properly in multiple room folios. More on this later.

The rooms were basic if dated - these would have been a good standard in the 80's or early 90's, but lacked modern conveniences such as the a master switch near the bedside to turn on/off lights. There was a good view of Mt Merapi and at least on the SPG and club floors the rooms were by-and-large clean. 

One exception: the bathroom was generally serviceable, but bathwater was murky and a greenish brown, so I wouldn't recommend trying to get clean that way. Water temperature also inconsistent. Not sure if it was a problem with the hotel's water system or just typical of Yogyakarta. Toiletries were very unimpressive - some generic shower gel and shampoo that didn't even bear the Sheraton marque.

My room at the Sheraton Mustika was about 20 feet from the lounge (where I had breakfast and evening snack/drinks). The selection of food there is barely sufficient for a meal (and won't be mistaken for anything else). There was a single countertop and island in the lounge, stocked with one or two hot dishes, fruit, and cake. Complimentary alcohol is served in the evenings, though this is limited to red wine (which did not try), white wine (which tasted like an overoaked chardonnay), and Bintang beer (the best option).

The lounge was very empty - throughout my stay there, I saw four other guests there (one Chinese couple with their child and an Eastern European lady).

I looked at the pool (which looks more like a large outdoor fountain) and decided not to use it.

I used the gym (aging equipment, but serviceable) and had a massage - both did the job, but were unexceptional. 

To be honest, at the price the hotel is nothing to complain about. For a Cat 1 hotel it is exactly what you would expect. There are mosquitoes -particularly in the evening - and I'd suggest bringing repellent if you are staying for any length of time.

My main issue was that after I checked out, I realised that contrary to my request at check-out two of my rooms had been put on a single folio, and one of them had been recorded as a redemption rate (the other room was credited with the full spend and points of both rooms, so ultimately I had the correct number of points and stays/nights credited - but it was still baffling). To date this has not been corrected (despite reaching out to both the hotel and the SPG team).
