I stayed at the AKVO for 2 weeks for business in both the Garden and Executive Suite. I had previously stayed at other properties in Central and it was impossible to find a decent room without overpaying by quite a bit. I happened to choose AKVO simply by word of mouth so my expectations were low.
Let's just say I was blown away by how good AKVO is. The service was top notch all the way through, from the cleaning staff to upper management. The suites themselves were the same as or beyond any other 5 star hotel I had stayed in Hong Kong (including the top range of the big chains) The design and quality of the materials, the furnishings, lighting, flooring, technology, shower-head, toilet paper, etc. were all top-notch. I learned that this building was first intended to be luxury apartments but converted to a hotel quite late, which explains the quality of the fittings.
The Executive Suite on a high floor has a gorgeous 270 degree view, plus a very enticing sauna, which I sadly did not get the chance to try. The Garden Suite on a lower floor has no view but a large verandah plus outdoor jacuzzi. This was the main difference as otherwise they were quite similar. Personally I preferred the former as it was much brighter with natural light, rather than looking into office buildings. The Garden Suite could really use an awning as well to give some privacy.
Location wise, it is a 10 minute walk to the Landmark in Central, is gastronomer's dream. There is so much to choose from within short walking distance in every direction and I basically ate a different cuisine every meal.
Like others have said, this is a small boutique business hotel, so do not expect a pool, room service or so on.
