Mario's place was in an excellent location, super close to many major sights and also to a metro station, making it very easy to get around. The flat was in an impeccable condition with amazing views over the city and was furnished to a very high standard. Coffee pods for the machine were provided which was a definite plus! Mario as a host was excellent - he responded fast to any messages and made sure the check in was a very smooth process despite me having to change the time at short notice. Overall, an excellent stay and I would definitely stay again in future visits to Madrid!
