Miguel was really communicative, which made the booking and check-in/check-out really easy. The apartment is in an amazing location. Right in the heart of the old city, near museums and transport. There are some lovely little restaurants and bakeries close by.
Do bear in mind that it is an old building and so there are little niggly things that might bother some. The toilet plumbing means that it's best not to put toilet-roll down the loo. This is not a problem as you can empty the bins outside the block after 7pm each day.
As others have mentioned, the door key has a personality of it's own, but once you get the knack, it's fine.
A couple of things which I've mentioned to Miguel, so hopefully they will get sorted. The shower room isn't brilliantly ventilated, so that needs fixing and a chest of drawers are needed in the front bedroom.
However, in terms of communication – he came straight over when we needed him, location and value, the apartment was great!
