The check in process was very easy and the hosts were very thorough! There are instructions for everything. The apartment is very cute and VERY well stocked and everything that you could possibly need (Check out the letter from Marilyn Monroe on the living room wall.). The bedding is of good quality and the beds are comfortable. Lots of dining nearby and very close to the metro! Overall, this is a great base for your visit to Madrid. Would visit again and would recommend this for anymore.

My Personal Tip: Bring your running shoes and go for a jog in Retiro! Amazing location for this.
