It's a very nice small and cozy place in the heart of Madrid, close to everything. It's well-equipped and tastefully furnished. I would say it's perfect for a short-term stay of up to 4-5 days. It's freshly renovated. The host was very helpful and the check-in process went smoothly. You receive a digital key that you can use from your mobile phone, so you don't need to meet the host to get or leave the keys. The only downside of this place is that there is another apartment for other guests just behind a small thin wall (it was probably one big apartment in the older times). We were a bit unlucky that some very noisy British guys were staying there at the same time, so we heard them till midnight almost as if they were in the same room. It's not the fault of the host, though, as he clearly stated no partying after 10 pm. I'm still giving this place 5 stars as we were completely satisfied with everything and the noisy neighbors left the next day :)
