Gloria's place is fantastic. The location is perfect, just a couple of blocks from Obrigen and surrounded by nice restaurants and cafes. It's very spacious and has everything you would need for a long term stay. The host/security guard at the apartment building was incredibly flexible and accommodating. He helped us carry our luggage up to the 3rd floor that the apartment is on, and they were very flexible letting us use their parking even after we checked out of the airbnb. We appreciated his help a lot!
One thing I would have liked to know beforehand is that there is a very popular restaurant downstairs, and the kitchen from that restaurant exhausts their grills right into the area where the apartment windows are. Since the apartment can be a bit warm, this meant we had to smell the steaks being cooked in the kitchen until midnight every night. So be prepared!
