We stayed ten days at Jeff's and Aron's place and I definitely can recommend their place. Jeff is a very good host, friendly, helpful and easy to get along with. We got lots of useful tips from him during our stay. The location was perfect; close to the Farmers' Market and Deep Ellum. The central Dallas was withing walking distance, including the Americal Airline Center.
The ensuite room was spotlessly clean and a bed was very comfortable and ensured good night's sleep. The room had also a fridge and a coffee maker and we were able to use their kitchen and utensils.
We hope to visit Jeff's and Aron's place again soon! This place is a gem.
