Check in is nearly 2 miles away (€15 taxi). And you need to be there before 20.00 or you'll be charged another €40 and have to travel another mile or so. Addresses are stayed in the fine print, but just beware you'll have to do a cross town journey just to check in.
Once in, expect little sleep due to noisy neighbours in apartment 1841. I have videos of them partying loudly until at least 1.30 as proof. Not great with the thin sliding doors that make up the "walls" of each appt. Lights didn't always work, plug sockets intermittent, lift shaft smells of gas.
We went with 2 kids and expected 2 decent nights sleep, or at least rest. Nobody got any sleep - or any rest. Shower leaks, pillows stink due to not being washed. We paid €150 per night. Don't. Book early and find somewhere nice...
