I'll preface this by saying that the 2 guys at service were phenomenal. They answered my wife on any question she needed about the room or about travel to/from Mestre/Venice and helped carry our bags up the stairs.
The bad? The bed was a little uncomfortable (but, maybe that was me?). There's not much to the shower in the bathroom (which, is communal by the way), the windows in the room were hard to close, but, if you did, not much air movement happened, otherwise. If left open, get ready for some major mosquitos to come in. We had plenty.
And also, there was a lot of noise at night, even sometimes after 10 with a lot of people yelling. Could be hard to sleep at some points and luckily quieted down through the night.
Overall, it was an alright experience. In my book, service is key. And they did that perfect. Otherwise, comfortability lacked a little.
