We spent in total 3 nights at Verónica’s place. She greeted us at the doors and explained the surroundings. Whenever we had questions she immediately provided answers.
The apartment is perfect value for the money however please note that it can get quite hot without AC turned on and the only windows are open to the interior passage which is mostly shadowed - so not much sun :(
Overall we rated this place 4/5 - what we didn't particularly enjoyed were problems with the keys to the outer door and noisy neighbours (2 nights).
Perfect place to enjoy a night live in Madrid.
