My boyfriend and I stayed for a week at Long's house and I can say that the stay was very enjoyable. The location is very close to the metro station and bus station (5 minute walk), as well as a market, CVS, 7 eleven and restaurants all around.
The room we stayed in was spacious and had everything described in the listing. The only detail we found was that in general the room and/or bathroom had a not very pleasant smell and the days we stayed there was cold but the heater for some reason was turned off and did not work all night so we were cold (and no extra blankets included).
The communication with Long was very good and he helped us with everything we ask to.
Overall, I think it is an ideal place to stay either for a short or long time (although be aware that it does not have a kitchen if you plan to stay longer), very well located and in a quiet neighborhood. We highly recommend it.
