I can really recommend Jorge as a host and this apparment for your stay.
It makes you feel like home and its' location is almost perfect with an awesome metro connection and the short ways to the restaurant-, shopping- and river area. Eventhough it's close to these areas, there is no huge noise level or sth..
The description you receive to get there is very, very detailed and everything inside the apparment worked perfectly (WiFi, TV etc.).
Once we had a small issue with the showerhead which was fixed totally uncomplicated and within hours even in our absence.
To sum it up: This location made our trip even more perfect.
