Andrei's place was very nice, clean, and located in a great area. We mostly walked to and from the apartment to many other parts of the city where there were things to see and do. There are a lot of lovely restaurants around the apartment -- perfect for brunch (we went to Manzo's and it was delicious). As for things to see, visit the cemetery in Montjuic. Not a lot of people know of or go there, but it's on a hill and gives an incredible view of the whole city on one side and the sea on the other.
