This is a pleasant enough place in an apartment block seemingly owned by the same rental company. I booked it last minute so it was a life saver for me but as a tall (188cm) person the attic style of the space I was in (fourth floor) was a little limiting and felt a little cramped. The furnishing etc are fine and comfortable but parts of the apartment are quite old and not in too condition. My main complaint was that it was pretty cold throughout - there’s warm air via the ac and a small portable heater but it didn’t feel great to have to have those on most of the time. I think it’s just Madrid apartments maybe that don’t have heating? It was winter of course but still quite warm outside (14 - 17 degrees). Oh and the walls are very thin so I could hear neighbours very clearly. Not that noise was a problem I really The roof terrace is small and basic but a nice spot of the sun is out. Overall would recommend — but maybe not for very tall people :)
Ps the proximity to Retiro is nice if you like parks / running and it’s also good if arriving by train. Communication was generally very good.
