I stayed at Reina's place for several weeks and can honestly say it was a fantastic experience. Reina is extremely kind and attentive as a host. She and her family live upstairs and rent out two rooms downstairs, so you are all present and can communicate easily but also not be prominent in each other's spaces. It's in a quiet street Allston just a few minutes walk from TJoes and Starbucks, and then about 20 minutes walking to Harvard square or slightly longer to Central. The location is great, extremely convenient, quiet, and the house is tidy, clean, and quiet, too. Reina stays extremely on top of cleaning and everything in the house is clean all of the time. I really couldn't recommend staying with Reina more.
