The apartment is in a brilliant location - very close to Gran Via and the trendy neighbourhood of Chueca. Plaza de Pedro Zerolo is on your doorstep and it is a great place to soak in the atmosphere of Madrid.
The apartment is very clean, safe and secure, with good A/C and large opening windows to let in fresh air. The bed is a double, so for larger people or a couple you may find it a bit small.
Although we didn't meet Íñigo in person, he was very responsive by messaging, and was kind enough to let us check in early.
If you want to be in the midst of it, yet retain your independence and privacy, this is a great option for your accommodation.
