Mariana’s place was in a really good location in a nice building. There is a dedicated bathroom, but it's not attached to the bedroom. She does have 2 dogs which were not part of the description - they are super well behaved and sweet, but might be a problem for people with allergies :)
Overall she was a great host with fast communication. The negative feedback I have is that she had guests over one night who were pretty loud and kept me up until about 3:30am when they left. It was pretty unfortunate because I got sick during my trip, came to the room early from my event specifically to get more sleep to recover, and obviously couldn't.
