We stayed in the apartment for a week. We were very pleased with it and had a great time using it as a base for our explorations of the island.
As it has an elevated position it has pretty good views over the city and to sea.There is a lower entrance (which can be reached by stairs and a lift) which is a better access leading to Paseo Chil and then further steps for the old town.
Unfortunately I think that this apartment would be unsuitable for anyone with certain disability or mobility issues due to the steps to access it.
To reach the apartment I would recommend following Gerardo's directions as there are many one way streets in the area which are initially quite confusing. There was more than adequate parking along the road at the top entrance.
The pool was drained for maintenance work during our stay-so we didn't use. This wasn't really a problem to us but could have been an unwelcome surprise for anybody with their heart set on using it.
