I enjoyed my stay at Rosa's appartment. Appartment has excellent location, is clean and safe. Sometimes you hear a few noises from the street at night, especially in the summer I think it would get busier, but it is located in a very good area and in general is very calm to sleep. Note that you share this apartment with the host completely and the host is also usually at home. Therefore she has certain house rules that she expects you to live up to as where to put your stuff, how to use kitchen supplies and she also cleans mostly again after you. If that's not what you like, I recommend an appartment just for yourself.
