As we arrived late in the evening, it was very convenient to just cross the train track and be at the hotel. Even though the trains pass right outside your window, it is absolutely fine, as they don't run at night.
There is a bit of a humidity problem in the bathroom, which is mainly due to poor ventilation, as the bedroom is totally ok. This wasn't a big deal, as we kept the bathroom door closed and only stayed 3 nights in Aguas Caliente.
The breakfast is simple, but sufficient.
Since cleaning isn't done during your stay, the bin in the bathroom isn't emptied either... so, we asked for a new bag and just put the old one outside our room.
