Service is super, services need support.
Stayed at the Eastgate Tower for nine nights. Chose it because of the affiliation with the Affinia brand, which I love. It's not a true Affinia experience though.
The employees were lovely, helpful, everything you'd want. The room sizes were great. The whole experience was efficient and the location is ideal for reasonable rates in a central area. Amenities and attractions were simple to walk to or from Grand Central which is three-ish blocks away.
Where I take stars away is the appearance and finish of the room. The Eastgate is overdue for a facelift and i felt like we were staying in a forgotten apartment. The cleaning wasn't ever consistent and there are nooks and crannies that look long since forgotten by the scrubbers. The gym is a joke (five old machines in a room with the TV you have to blast to hear over the whirring).
In all, if looks and amenities don't matter much to you, the Eastgate might work. For now, it's off my list of NYC properties. Would certainly reconsider if they renovated though!
