Apartment is in a great location just a few minutes walk from Principe Pio which makes getting out and about quick and easy on the efficient Metro.
The apartment had most things you need for a bit of basic self-catering (just breakfasts for us) but it would be difficult to prepare any meals as there are no work top surfaces, just the table.
There's a couple of lifts in the building - apartment is on 6th floor - no views but nice and quiet, especially at night.
Bedroom is small but enough space and storage for 2 adults.
We didn't meet up with the hosts but they were always quick to respond to emails and were very obliging about our check in and check out requests. It would be helpful though if at least some basic information about Madrid was left in the apartment - for example maps, guides, local details, etc. Also a note of the wi-fi codes which worked fine when we got these.
Madrid is a great city and well worth a visit.
