Sandra's place was welcoming and wonderful. Perfectly located in a central area next to the train station and subway with multiple coffee/pastry shops below. Sandra met me at the apartment and left a delightful welcoming set-up with apples, chocolate, peanuts, water bottles, and (most important) Port wine. It was very appreciated by this road-weary traveler. She also had a quite helpful book that I used to find a couple of wonderful restaurants (Flow was amazing).
The only thing I was apprehensive about at first was the possible noise. The negative aspect of the central location was that there was quite a bit of street noise below. This is the odd thing, though: I am an extremely light sleeper, yet the noise did not really bother me at all. I did not even use ear plugs. Maybe because I was exhausted from traveling, but I was able to sleep fine in Sandra's place. I would definitely stay there again without hesitation.
