The location of the apartment is great. It is near the famous Schweppes building (Gran Via) and you can easily walk from the apartment to all the touristic places. It is also very close to several metro stations. The building has a small lift, which is great if you have bags/luggage.
The apartment was very clean, it had all I needed for my short stay: Dolce Gusto coffee machine, kettle, toaster, kitchen, washing machine, cutlery, hairdryer, towels, shampoo, etc.
Checking in an out was easy.
The communication was good, when I had question they didn't take too long to answer them and the instructions for all the process were clear.
I would stay here again.
