This apartment is absolutely fantastic. As others have said, the location and views can't be beat. Yes, you will do a LOT of climbing getting around the neighbourhood, but we appreciated the exercise! We walked to many of the key attractions from the apartment. Please note that it would be difficult for someone with mobility issues (or with a stroller) to navigate the area.
The apartment itself is very clean and well equipped. The beds are comfortable enough and the bathroom is very nice, with great water pressure. The A/C was very welcome! There is a washer in the apartment but no dryer. I am not sure if there was a dryer somewhere else in the building...
Our only issue with our stay was that it was difficult to communicate with the host in the weeks/days leading up to our trip, which was a bit stressful.
