The listing is right between Line 1 and Line 3 which allows for easy maneuverability in the city. The room can be a bit cramped, but it is not too bad. The room is stocked with a small kitchen which was nice. The large open window made for great evenings when we returned.
The two main problems we had were the fact that the wifi hardly ever worked for us. It was sometimes inconvenient as we had to wait for the wifi to kick in to work out where we were going and the route we were going to take. The other problem was the short duration of hot water. Myself and two others had to wait around 45 minutes between showers for the hot water to last a 7 minute shower.
Other than these two problems we had a great time. Carlos responded quickly to our questions and the room was enjoyable (except the two problems listed above).
