First impression might feel like it's something super-beginner and uninspired, due to ugly blocky street section and the monastery outskirts, but inside it's much better. It's a multi-floor structure with A LOT of guards, an alarm (that you can't disable once it goes off, as far as I know, so be aware) and many rooms, where you will be searching for keys and levers. All of that is designed fairly well, giving you enough options.

I'd suggest to avoid triggering an alarm. It will be blaring in your ear the whole mission, which can take up to an hour to complete. If there's a way to turn if off, I didn't find it.

Pretty solid experience overall. Probably worth trying.
