I stayed here for a few days with my girlfriend to explore Madrid and everything was wonderful. The apartment looks just like what you see on the photos, everything being neat and tidy, Renan also left us a welcome package of various drinks which was nice. There was one of his colleagues waiting for us upon arrival and everything was explained in detail. Great choice of location as well, we were right in the centre of Madrid with easy access to all the major sights with an underground station not even 5 minutes away which was also very convenient.

The only downside (really a small one) was as mentioned in a couple other posts, it takes a bit of effort to open the front door of the building to get in. The first night of our stay we couldn't open our door, but we called Renan and someone came in 10 minutes to open it for us and explained what to do, you have to push the key slowly in / out, up / down, left / right, basically wiggling around with it until you hear the clicking sound from the lock.

Apart from that really nothing to complain about, it's a great place and I highly recommend it to anyone wishing to explore Madrid.
