Cesars place is in the Las Lettras neighbourhood which is walking distance away from Madrid’s art galleries and full of pubs and restaurants. I was expecting to enter someone’s home but it appeared to be a hostel with private rooms. No issues with that since I was a solo traveller, but it did feel a bit lonely at times. The room was small but clean and zero frills. It also has a private attached bathroom with running hot water (which was honestly the best thing about it!) I didn’t spend much time in the room except to shower and sleep so would recommend the same to solo travellers who are looking for the MOST basic of comforts.
