We did not have consistent hot water for 2/4 weeks of our stay. The system has been entirely replaced now, so that should no longer be an issue. The apartment is owned by a rental agency that seems to us to be impersonal and largely unresponsive. The apartment was not comfortable or homey, and we had to request a mattress topper because the single beds were so uncomfortable. My friend slept on the couch for the first two weeks instead. Our stay was generally okay in terms of safety and location, but not what we hoped for. We got a partial refund for the hot water, but our time in Barcelona was negativity affected.
