Location was perfect, was very close to all of the action downtown and walking distance to all of the major tourist places. Was also only 10 minutes from the metro line for getting back from the airport. The communication was perfect - very fast and easy to talk to. Host even allowed me to have a portable wifi device delivered a few days prior to my arrival so I would have wifi while I was out exploring.
The only issue was noise which I think might be normal for the area (loud radio music as there is a bar directly outside the front door), but there was also a lot of noise from within the building starting at 7am. This is not a fault of the host or this unit, I just wish I knew about it beforehand as I am a very light sleeper.
I would definitely stay here again, would just bring some ear plugs with me
