The apartment is located in a great spot. It is close to many attractions. Many supermarkets near you and the kitchen is set up to prep meals. We would have breakfast. The Santo Domingo metro station is basically right outside your door. You can take the train there from the airport. (We got the 10 ride + a supplement for each person in our party.) As far as sleeping arrangements go, it is comfortable. Couch is quite comfy. It is a bit noisy at night but if you’ve been sightseeing all day it might not bother you. The only negative was the washing machine was not working. They were waiting on a part. Overall it was a great experience. But if you check in after 11pm you do get charged 15euros.
