Elda's apartment was perfect for our 5 day trip! It was very central so apart from getting public transport to and from the airport, we walked the whole time.
The apartment was very clean and had everything that we needed. Beds were comfy and shower was good.
Elsa was very helpful and gave us some good tips of places to eat and to see.
And she was even kind enough to hold onto our bags for us on the last day as we had a late flight.
I would definitely recommend this apartment to anyone visiting Madrid. It was perfect for us- thank you very much Elsa!
