We really enjoyed our stay in this apartment. It matched the photos and description accurately, and it was in a great location. I estimate it's about 2 mins walk to a cool bar called Preachers, 3-5 mins walk to some nice coffee spots and cafes, and about 5-7 mins to Salamanca Place/Markets and the ferry terminal for MONA. There is a slight incline when returning to the apartment from Salamanca Place, but I believe most people would be fine to walk this.
We had no trouble getting Ubers in the area, and though it is near a busy street and some nightlife spots, we weren't really disturbed during the night from any traffic/people in the streets. The area itself felt safe, and though there were several other apartments in the building we never heard any other tenants/guests.
Our only drawback was that the hot water ran out quickly a few times - we think it may be shared with a few of the other apartments. We just made sure to shower when we couldn't hear the pipes already going and kept it quick to preserve the hot water.
We would absolutely recommend this place (especially if planning to visit Salamanca Markets or take the ferry to MONA!), and would happily stay here again.
