Incredibly easy to arrive and pick up keys. The apartment is small but extremely well set out so it doesn't feel that way at all. It's a great apartment in an extremely well located part of the city. It makes it very easy to go to Mercado San Miguel, Palacio Real etc. At night the windows block out 99% of the noise so don't worry about it being centrally located - you'll easily get a good night's sleep. We would definitely stay here again any time.
