Black swans

Monday 
We decided to use the hop-on, hop-off bus today to have a bit of a rest. Somehow we managed to book the wrong thing and ended up with the city tour instead, which meant we were stuck on the bus for an hour and couldn't use it to save walking as we'd intended.
It was very hot, so after the bus tour we headed to the Retiro park for some shade and cool drinks. 
Out to the Sol area in the evening for tapas. We shared a paella this time.
