I'm not going to be able to comment on the average room because I stayed in a business suite here, but I can say that it's a short walk from the central market and the main centre of town, the service was lovely (if a little slow) everywhere, breakfasts are comprehensive, there's slow-but-steady wifi in the lobby, bar and restaurants and the wired internet access in my room was fast.
Obviously it's a pricey option, but you get what you pay for in Myanmar.
In the usual "international hotel" way, food, drink and other services within the hotel are "internationally priced", but there's a good supermarket upstairs in the plaza right next door.
Yangon itself is a charming city (in a way that Mandalay really isn't), but you'll definitely appreciate coming back to a nice room (and a swimming pool), so I can recommend that if you've got the budget it's worth paying a bit more and having a nice base to explore the city.
The doormen here can be relied on to get you a fair taxi price too.
Nice hotel in a good part of Yangon, I'd thoroughly recommend it if it's within your budget.
