Just finished a 30 day trip and here are some updates:
Prague / Carlo IV, The The Dedica Anthology Autograph Collection / No Lounge; Breakfast in restaurant - The only thing I would add is they will cook eggs to order but they don't promote this, so you need to ask.
Bratislava / Sheraton / OPEN - the only thing I would add is that breakfast is included but served in the restaurant (as noted in sign in the lounge) and is a very nice buffet with an egg station for eggs cooked to order.
Madrid / AC Santo Mauro, Autograph Collection / No Lounge; choice from 3 types of continental breakfast - confirmed. Also an upcharge of €13,20 to order a la carte.
Brussels / Marriott Grand Place / OPEN; key accessible 24 hours. Yes, it has monitors and printer but no computer connected to them or if a computer is connected then it is turned off. Front desk will print things for you but you need to email them the doc or email. Breakfast is in restaurant with an egg station for eggs cooked to order.
