Our stay at Diogo's place was very nice. There was a slight issue at check in, but Diogo was very responsive and got it taken care of quickly. The unit was very clean and comfortable and had everything we needed for our 3-day stay.
Only complaint I have, as some others have mentioned, the surrounding area does not feel very safe. But, the building is secure and I felt safe staying there. Overall, I would rebook here if I ever come back to Boston.
