We were warmly welcomed by the host. He gave us all the details that we need and recommandations about places to go. The messages prior to our visit were responded very quickly. The apartment is as exactly as it is shown on airbnb, wifi is good too. The location is excellent, really close to the train and metro station. It's a really convenience and nice neighbourhood. The only downside was prob the hot water for shower. It takes quite a bit of time for hot water to boil. Also, there are no lifts so it is a bit inconvenience for people with heavy luggages.
I would definately recommand this apartment for people whi wants to have a nice place to stay in Madrid.
