Andrea’s place is in a great location, right in the middle of so much to do in Madrid. She was an exceptional host - she prepared a baby bed for our son, provided us with restaurant recommendations, and had her co-host wait patiently for us when our flight was delayed making our arrival to the apartment time much later than anticipated.
With the location being so good, there is some street noise. But if you just stay up and have your dinner a bit later as the Spaniards do, the noise dies down before bedtime.
The apartment is on the first floor - just one up from the ground floor. It was very nice to have an elevator with our son and his stroller!
