My fiancé and I stayed here for a month and overall we would book with Urban Nashville / Pine St Rentals again - though fair warning that this unit does get some noise.
The space itself was great - it was much more spacious than expected and it was extremely clean. The condo is in a very large apartment complex and the amenities - like fitness center, pool, parking garage - are a nice bonus. The location is excellent - you really are right in the heart of the Gulch! The team at Urban Nashville were friendly and responsive - we had a couple things pop up and they handled them immediately.
Unfortunately, the floors/ceilings are thin and the apt above us was consistently quite loud, though this is no fault of Urban Nashville (and the team graciously tried to help us address this with some, but not total, success). I will also note that the unit directly faces the train tracks and gets noise from the trains and construction nearby, so I would take note if you’re a light sleeper or think this will bother you. Some reviewers said that the trains didn’t disturb them so this may just be personal tolerance.
Otherwise, as mentioned, we would book with Urban Nashville / Pine St again but maybe in a different unit of theirs - it was still a great space in a great location for great value.
