I stayed for one night and the hotel is very nice. It's not far from the center of the city. Breakfast was included and on an upper floor so there was a view over the river. Wifi worked fine and there was a minifridge in the room. My room also had a small balcony, but since it was winter I didn't use it. Like most places in Paraguay the window doesn't seal so I could see bugs being an issue in the summer. While the hotel is clearly older, it's been maintained well and has a very nice looking lobby.
