The location is the best that you can get in Barcelona, conveniently close to the Metro, bus and shops, it's easy to travel around both during the day and the night. Via the Metro stop Monumental we managed to explore most of Barcelona easily and also have time to shop locally. The flat is definitely ideal for two, max three people. It being a ground flat you don't have to worry about lift or stairs (expect the ones that lead to the bedroom). They hosts had a booklet with tips and info which was very helpful.
