I had a great stay in Madrid. The flat is very centrally located but still quite quiet. It is very well equipped and comfortable. Veronica was very helpful and attentive. It was really easy checking in and out. Definitely recommend.
If you are tall, you may be tight getting into the loft. I’m average height for a woman and it wasn’t a problem, but if you are a tall man you will have to duck to get into the bed on the mezzanine.
