This hotel is absolutely lovely. Really enjoyed our stay here. It's in the perfect location to spend the weekend exploring Madrid & ideal if you want to be in the hub of restaurants & bars.
Loved our room too. The balcony was very Spanish and I enjoyed standing out there, watching the world go by. The bed was very comfortable, with extra pillows if you wanted them. The shower was perfect. There was plenty of space, & the style of the room was very modern.
If I had to give one negative, it's the noise. Now, the outside noise is addressed by sound proofing & if you use the shutters that's an extra layer too so you only hear it as a murmur in the background. The noise from the restaurant though (& the cleaners in the morning), can't be drowned out unless you put the TV on (normal volume does the trick). That said, if your routine fits Madrid (i.e.: you go to bed at midnight or later & you're happy to wake up at 8.30am/9am) like we were, it won't be an issue for you; it wasn't for us. However, if you like to be in bed by 9pm or 10pm on a Saturday night, it might bother you.
If we return to Madrid we'll definitely be staying here again.
