Belém is kind, energetic, friendly, informative and generous. She was extremely welcoming to me, and communicated well and promptly with me prior, during and after my stay at her home. She was gone most of the time, and I (and her dog) had the apartment to ourselves.
The apartment is in an amazing residential neighborhood a block away from a cluster of stores such as bakeries, food shops, whole-grain store, general convenient store, huge supermarket (Carre Four), a lotteries (place where I could recharge my bus card), a pharmacy etc. The apartment is set back from the street, and I found it very quiet. There were major bus lines within a block or two of the apartment going to almost every part of town, and I was able to get downtown in about 12 minutes. The room itself is a good size and has an amazing set of shelves along one wall which makes it ideal for putting stuff away. There's also a huge desk in the room which I found helpful, and a very large closet with a lock.
I would definitely stay with Belen again!! However, I do not think this would be a great fit for someone who is not comfortable with dogs, or for someone who is compulsively clean.
