Claudia's residence is central -- you could get to anywhere in the city from there and the neighbourhood is well-served by a regular tram service, as accurately described in the listing. Even on foot, it's easy to get to the nearest square.
Claudia's apartment is a breath of fresh air. It's pretty and quaint, complete with amenities and very clean. Its little nook of a garden is a hideaway in itself, a small world. The expression 'a home away from home' is a cliche but that's what the apartment is! It's home. When you've trudged through a few cities it's always such a relief that the next lodging is at least comfortable. Claudia's apartment really is more than that.
And, try the neighbourhood restaurants where the locals dine. Claudia recommends Zapata -- you have to book ahead as it's always full. But just a few shops down the same road, there's an unnamed little restaurant. The menu is varied, the food simple and really rather nice, and the service warm. Try the Portugese tarts in one of the shops along the same row. We kept going back for more!
