We arrived in Madrid by car; we found the apartment very easily and one of Melvin's colleagues met us very quickly to give us the keys. There is a parking station just 50m away, which made things very easy. Like all of the other posts mention, the fridge had complimentary drinks and there was also a bottle of wine for us. This was a really nice touch. The kitchen was also well equipped.
The apartment is very ideally situated in the Southern part of the Malasaña quarter. We really liked the atmosphere of this this area that allowed us to plunge into Madrid life with its numerous cafes and small shops without being too touristy. The apartment is also just 100m from the shopping strip of Via Gran. There is a metro station 100m away so getting to all of the top sights was really easy.
Melvin suggested this apartment to us as the one we had enquired about was not available. Unfortunately the apartment is showing many signs of wear and tear, particularly the bathroom, the sofa bed and the chairs. The apartment also only has two windows that look out onto the walls and windows of other flats, so there is really very little light that comes in. We only stayed a couple of nights and we were basically only there to sleep and have breakfast so we weren't too bothered by these downsides but it is not the comfort that I would be looking for for a longer stay.
