You cannot go wrong with Maria's apartment. It is a lovely, comfortable spot approximately 5 minutes walk from Sagrada Familia and the metro that is just a few short stops to all the highlights of Barcelona or within walking distance if you like.
There are bakeries and restaurants just downstairs from the apartment and the balcony has a wonderful view of Sagrada Familia.
The rooms and beds are comfortable (we are a family of 4), the kitchen and bathroom facilities are modern with no issues and the building has a lift for those who cannot walk up stairs.
Maria is an extremely friendly and caring host; she waited for us to arrive after a late flight in and went out of her way to ensure we had a warm welcome.
Maria is extremely reliable and responsive and an all round lovely person.
We would definitely stay here again. 5/5
