This place is in a good location near the Opera Metro and the Opera house itself. This is midway between the Royal Palace and Plaza Del Sol. The unit is on the 5th floor without an elevator so keep that in mind it may not be suitable for everyone. Being on the 5th floor is useful to keep the street noise to a minimum. There are restaurants and shops nearby. I recommend DIA and Aldi as the best value in local grocery shopping. For getting a local SIM card for my cell phone I used Orange found in Plaza Del Sol. The WiFi that comes with the apartment worked very well and is good to help reduce the use of data on the SIM card. I hope you will explore Madrid and consider staying at this location. Cheers, Jason
