The host neglected to inform us there was construction going on right next door, pounding and circular saw starting about 8:30 a.m. and going until about 6:00 every evening. When I messaged him about it, he actually told me it would not interfere with our vacation, and didn't even offer us a discounted rate.
The entire place reeks of mildew, and the bedroom was especially bad. There was no top sheet on the bed, and the pillows were a joke. The toilet leaks water onto the bathroom floor, and there's very little hot water (you have to turn the shower off while you lather up or you'll run out of hot water). The power outlets are also a joke, the slightest movement of the cord and whatever you've got plugged in falls out of the outlet. The doorknob to the unit either doesn't lock at all, or you get it locked and it takes you 10 minutes to get in/out.
The only positive thing about the place is it's view; it does have a spectacular one of the Douro River. A lot of rehab and it could be a pretty nice place.
