We spent an enjoyable week at Maria's place. The apartment is located in a beautiful old building in the heart of the old city but its tucked away down a small street so is away from the hustle & bustle. It's well located, with all of the main points of interest are in easy walking distance.
It was a little smaller than we expected, with the kitchen in particular being tiny. There's only a two ring hob and a microwave so it isn't ideal if you are planning on doing lots of cooking. But it is perfectly fine if all you want is somewhere to make a cup of coffee or a quick breakfast.
