Italian passport (no need of letter of invitation): Applied for Visa on Friday morning, got the Visa on Tuesday, 55 USD
Brazilian passport (with letter of invitation): same day issue (after making the payment in the bank -city centre-)
We went by green metro to Emler Akademiyasi and got bus n. 53 until Araz supermarket stop
We walked back to Baku centre by the coast path, it's a nice walk and took us about 1 hour 15 minutes
Thank you Caravanistan for all the info
