The apartment is at a great location from which to explore Barcelona. It’s across the street from the cathedral square, the city history museum, around the block from Santa Caterina market, and all sorts of restaurants and cafes. As far as transportation, it's close to the metro and nearby a taxi stop.
The place is comfortable and well decorated to make it feel like home. It’s attractively furnished, including a large flat screen TV. The artwork on the walls are reproductions of paintings in the collection of the Picasso museum (also a few streets away). There is also a nice information folder with all the necessary info on the appliances as well as places to visit and restaurant recommendations.
Access to the apartment is by two flights of stairs, which might be an issue for some people but was not a problem for us.
The hosts are super friendly and highly responsive for when we needed extra information.
Overall, highly recommended! Five stars for this comfortable and wonderful place in Barcelona.
