María is a kind host with a stylish apartment nearby the Vilapicina metro station, including every other kind of practical facilities, such as convenience stores, bakeries, etc. It is a nice place, where she lives with her family.
Although kitchen is not included, María is able to provide you an electric kettle and some basic cutlery, which I'd consider am above-standard service, since it isn't included in your stay there (as I've already mentioned above).
Personally, I'd consider staying in her apartment even some another time in the future during following Barcelona trips, even though I'm a financially irresponsible Czech student, for whom travelling definitely isn't cheap.
