We really enjoyed our stay at Mar's apartment, which is spacious, charming and well-located. The bathrooms have nice showers with plenty of hot water and the kitchen is well-equipped. It is in a safe area with several good restaurants and supermarkets nearby, for which Mar has prepared useful guides. The metro and bus stops are just around the corner.
The bedrooms face the street, which is not much of a problem since it is not a very busy street - we slept soundly. The two bedrooms with double beds are separated by a door, which wasn't an issue for us but if your fellow travelers are noisy, you may hear them.
Overall, we'd highly recommend staying at Mar's apartment. She is a considerate and thoughtful host, and we are sure you will have a lovely time here. We certainly did!
