The room is a good size for two people. It's not too cramped and the bathroom is a generous size. Great shower. The balcony is a nice touch. Note that there isn't any air conditioning and if you open the windows for air you'll get some noise from the city. Instead, you can use a small fan that is provided. There is a dishwasher, but note that it takes over three hours to wash dishes and no detergent was provided for it. The wifi was really bad. It was difficult to use it for email and researching restaurants, and almost impossible to upload photos. It wasn't the signal itself so perhaps just used by too many rooms or some sort of other problem.
When they say to not leave the key in the door they mean it; it's very difficult to get back in because a spare key cannot open the door when a key is in the other side.
The location is great. We only used the metro three times in a week. Plenty of local restaurants and shopping near by.
