I recently stayed at the Vibe Savoy for a week in April for a work trip. I found the staff were extremely attentive, helpful and pleasant.
The guest room is relatively small so you may find it a little squishy if there are two of you. As a solo traveler though, the space was completely fine. Whilst the decor may seem 'dated' to some, I thought it was perfectly fine. The overall room, bedding and bathroom were nice and clean.
Note: the shower was above which was not a problem however the bath is quite high so be careful when stepping in and out of it. There is a support bar installed on the wall to assist with this.
Value for money.
Convenience wise this hotel is directly opposite the Southern Cross station, has many tram stops nearby and a 10 minute walk to Southbank.
Food is average - maybe 3/5 but it definitely did not ruin the stay.
