I was lucky to spend a month at Marco's place. It was a great experience, he was a kind and attentive host, and most importantly the location of the flat is amazing, just on the border of touristy and residential areas, with easy access to both the famous sights and the local stores and eateries.
A few facts about the apartment that may be of use to future travelers:
- There is little direct sunlight. The apartment has no a/c but even on muggy days it never got hot indoors.
- All windows overlook other people's balconies. From time to time the people in neighboring apartments (tourists) can be quite loud, but the noise levels are still much lower what you'd get in the downtown area across the river.
- There is a large (somewhat hidden) Carrefour supermarket a few minutes' walking away; it probably has everything a traveler would need.
- The bathroom may appear small, but it is fully functional and easy to get used to.
Overall, Marco's place was amazing and I would gladly stay here again!
