I was attending a conference at the bigger, plusher, shinier NH Eurobuilding nearby, but they hadn't got any rooms left, so I stayed at NH La Habana instead.
It gave the impression of a busy hotel with high nightly turnaround, which would make sense given its proximity to the football stadium, but as a result it felt rather impersonal and perfunctory.
I can't complain about the comfort of the room, the quality of sleep or the breakfast - all were fine, but nothing to write home about. The reception staff were efficient though there was a long queue for both checkin and checkout.
In a nutshell, if you need to be in that particular area of Madrid for business or a football match, this place does the job, though you won't be gushing about it to the neighbours when you get home.
