Let's start with the pros, the apartment is very well located, within walking distance to a great selection of restaurants, and walking distance to almost everything in central Madrid.
Cons, we were there in the heat wave it was 43 cel and the apartment has no AC, and the pool was unswimmable also I had selected the wrong dates by mistake and the host did not want to authorize the cancellation since they have a no refund policy (even if I tried to contact them 1 minute after by reservation) so that was a big fail!
