Welcome to the forum.
I stayed at Hopeland for 3 nights during my last Bangkok trip a few weeks ago in January as well as staying at Citrus Suites, Park Royal Suites and Lohas Suites.
Some of the issues with Hopeland were detailed by other guys in this thread. A few too many folks hanging around in the lobby all the time, some of them snoozing away on the sofas. My room was large and I had no complaints except for the bullshit dim lighting in the bathroom. It was so bad, they may as well have had candles in there.
I never tried their restaurant. No worries because a few paces away is the very solid Det 5 bar/restaurant which is open all day and serves from a big menu with modest prices. You can't go wrong with that place.
It is a bit of a hike down Soi 8, but they have a golf cart to transport guests to Sukhumvit. If you don't want to walk down Soi 8 to the hotel, you can take a moto taxi from Suk for 20 baht. During the day when the sun is beating down, that's money well spent.
Of the 4 hotels I stayed at, I would say Park Royal Suites and Lohas Suites both offer more bang for the buck that Hopeland. I think Citus Suites is overpriced for what they provide, but it's popular with many BMs.
In this price range, the best of all the suite hotels for mongering purposes is Adelphi Suites on Soi 8. Yes, they can be pricier compared to the other places, but if you can stomach spending the extra cash, it's definitely the best place to stay due to its location with equal proximity to all the lounge bars. None of them are a more than a 5 -10 minute walk from Adelphi.
