The flat was spacious, finely furnished and quiet. I appreciated the modern shower and the equipped kitchen (with a Nescafe' coffee machine too!). The host is very responsive and happy to help if needed.
Although it is not located in the very city centre, it is close to the Cuatro Caminos underground station, from which it is possible to reach Gran Via in approx. 20 mins. Near Cuatro Caminos it is also possible to find big supermarkets (one of which is open 24/7). I will certainly consider this flat for my next stay in Madrid!
