Irene's apartment is very cool decorated and recently renovated. It offers everything you need for a pleasant stay. Checking in/out was very easy and uncomplicated.
It is located in walking distance to the most important sights and surrounded by many bars, restaurants and nightlife. It can be a bit noisy in the streets but that is really no problem since the apartment is at one of the upper floors.
Unfortunately, the housekeeper who managed our check in didn't speak English, but in case of any questions Irene answered very fast.
Thanks for a nice time in Madrid!
