My boyfriend and I recently stayed at Hostel Babilonia for 3 nights, we really enjoyed our stay. We had a private room with ensuite bathroom. The hot water worked perfectly and the airconditioner was much appreciated as it's very hot this time of year in Montevideo.
Bed was comfortable, and room was quiet.
The only tiny issue, was that the internet signal did not reach our bedroom, but that just meant we socialized more. Like I said, TINY issue, as everyone who was staying there was lovely. :)
The ladies that runs this hostel are wonderful. Their children are absolutely lovely and their puppy Peanut, is a delight as well.
The breakfast was simple, but delicious and MUCH better than other hostels we have been at. The kitchen is available for all guests to use, just the basic rule of cleaning up after yourself.
Location is great, right on calle Sarandí, Ciudad Vieja's pedestrian street.More
