BCounter,
Can't tell you what to expect accommodation-wise as that would be dependent upon your individual contract.
The mix of FD crew is good. You will find both the cabin crew and flight deck very friendly (except for the spies).
Unfortunately, the airline suffers from the overridding rule of AAB whose idea of man management is a well-placed stroke from a baseball bat. You'll meet him and you won't enjoy it.
Flight Operations are a good bunch and DL is a good guy.
