Stayed at Irene's apartment for a couple of days during a short trip to Madrid.
The apartment itself is very clean and quite spacious for 2-3 people. Kitchen was fully equipped and the equipment looked quite new. Bathrooms and bedroom was clean as well. Nothing bad to say about the interior.
The location is absolutely perfect. It's right in the middle of the city. You're within a couple of minutes walking to plenty of tourist sites and local hotspots. Didn't have any complaints about the noise, even though it is in the city centre.
Check-in went super smooth as well. Would definitely recommend staying here!
