This is a great place to base yourself in Barcelona - on the beach so you can get away from the crush in the centre, but close enough with the bus right outside.
The space is pleasingly different in layout as well.
Things you should be aware of are that it is by a busy road - on hot nights this might be a problem, although there is AC. Typical of a modern refurb the ceilings have been opened up but this does make sound insulation between the flat and the flat above not very good - it wasn't a big problem but could be. Both of those points are things to be aware of not criticisms - the quality of the place is really good value.
Nu is a very good host - communication was excellent.
