MariCarmen is a great hostess. Very accommodating. She met us in the pouring rain. She secured a parking space for 15 euros/night in a parking garage. Location is perfect and across Old Town. The apartment is spacious and clean. The building has an elevator which is a plus. Windows open to the busy street but did not hear a lot a noise. I actually enjoyed looking out the window to see the people bustling around.
My only recommendation would be to maybe include coffee and tea. It's close to a lot of restaurants but if you are in a rush, a cup of coffee or tea from the apartment would be great.
