Mike is a great host, very easy going, helpful and super nice mate. He gave me a lot of tips to visit other close cities. He was very helpful in my 8 nights staying in Madrid. The flat is very well located in Madrid center, a few steps walking to the metro station but in Madrid you don't need to take the metro if you are there for a good period of time. His wifi is fast. Yes it is a small flat compare to the ones in the USA however you have everything that you need. Madrid is loud at night, people who collects garbage is very loud at night but that will happen anywhere in the City.
Thanks Mike, I will for sure come back and stay with you when I return to Madrid!
