My stay at Mercedes’s place was very pleasant - herself and her husband were very warm towards me.
They both gave good recommendations and the highlight of the stay was Mercedes already having a transport pass (you’d need to top it up) that I could utilise.
The location was very ideal for me as it was away from the busyness of the city but still had good connection to the city and the airport.
The apartment is a straight train (C1&C10) from the airport then a 10 minutes walk.
There are several buses (2 minutes walk from the apartment) and the metro (5 minutes walk from the apartment) that go straight into the city center
Mercedes has a cat (Calla) and a dog (Bruno) who are the sweetest - if you don’t mind animals
Overall, I enjoyed my stay!
