staying at Carlotta for 4 days was a good deal for a short holiday. the location is great because you can just walk to almost every attraction point. the place was very easy to chick in especially if you arrive late at night you don't have to worry about making someone awake just waiting for you. also Carlotta was very easy to reach and she responded fast.
the only thing that was not cool is the area can be very noisy from early morning until midnight, so if you are planning to stay in the room for work or relaxing in the daytime you should think about a more calm area. otherwise i highly recommend Carlotta's
