Fantastic location; extremely easy access from Garibaldi station, and nearby quite a bit of nightlife and restaurants. The place is clean and quiet if you want it to be -- or you can throw open all the windows and have a nice view of the plaza and the nightlife below (along with all the sights and sounds).
Loretta was helpful in answering some questions, and even showed me and the other guest around a little of the city. (Since I came alone, it was nice to have a housemate in the other room, so there was someone to hang out with at times.)
One thing to note: I was there during an especially hot period in mid-summer, and at night I'd close the window (it can sometimes get loud, especially on weekend nights). With the window closed, it was quiet, but the room can get warm. This didn't bother me much, but if you're one of those people that "need" A/C, it might be best to avoid coming in August.
Overall, I had a great time and would certainly recommend staying here.
