What a great first Airbnb experience. Constantine was very helpful and flexible, specially with check in and check out related matters. The apartment is very cozy and nice, just like in the pictures. It has everything we needed while in Madrid (and even more) I totally recommend this place to stay in and if I am ever again in Madrid, I will surely contact Constantine. The apartment is also very conveniently located, you can walk from there easily, but it is also near the metro station. Thank you Constantine for everything!!
