The apartment felt like home, it was warm and cozy. It is full of light, peaceful and extremely clean. Even though in the vicinity of one of the busiest parts of the city, the street is quiet and secluded. The neighbourhood is safe. There is a fantastic (reasonably priced) restaurant in the same street, the market only 10 meters away.
I stayed for 8 days and I can honestly say it is perfect for a longer or a short stay.
It is quite near the oldest part of the city center, about 10-15 minutes by foot. The subway station is a minute away. You can easily and quickly reach any part of the city from this street.
Rosa was always responsive, helpful, never disturbing, but there if you needed her. I have nothing negative to say about this apartment, even to come up with a detail that bothered me.
