First, Rosa was great... very responsive, helpful and friendly.
Apartment was as described, very clean, lots of room, high ceilings and everything in working order. It was comfortable to spend a time in, beds were very comfortable and was relatively quiet despite the building being on a busy street.
Location was fantastic in terms of being centrally located. The immediate surroundings had a ton of activity and it felt like the perfect base of operations to explore the major attractions that are dispersed throughout the city.
As other have mentioned, there is not a lot of natural light, but that is the result of being in the old part of the city where streets are narrow. It was not a big concern for us since we wanted to spend most of the time out.
We spent a week there and Rosa stocked some of the basics - sugar, coffee, salt/oil/spices, which is great because we did not have to buy that at the store and throw away leftovers. Carrefour is a couple doors down for anything else.
