We stayed at Leonard and John's place for two nights, and we had a very good experience.
We arrived late in the evening, and had some problems with the door. Even thoug it was late, they came down and helped us, which was really nice!
The place is very accurate compared to the pictures and description, and the location is really good if you wanna explore downtown Dallas and the Deep Ellum area by foot.
An overall very good experience, and we will definetly recommend Leonard and John's place to everyone who's interested in staying in Dallas.
