The apartment is well situated - close to Roma and to Zona Rosa. The downside is that it's on a very busy triple-lane busy road. Once you are in the building you won't hear the road so that's the saving grace.
The living doesn't get much light, but the two bedrooms are facing West, so flush with sunlight in the morning.
The hot water was an issue when I was there. The host gave me instructions to make it work, which is fine if you are staying just for a day or two. But for longer stay, you might run out of patience. I hope the owner will fix the issue asap.
Keep in mind that the walls are thin, so if you are are sensitive to noise coming from neighbors or dogs barking, I would probably not recommed this place.
Overall it's a good place, just keep in mind these caveats.
