Overall, a very nice apartment - I slept well thanks to the soundproofed windows and comfy beds, the shower had plenty of hot water and good water pressure, and the place was very clean and in good repair (those are my top 3 evaluation criteria). It is located within easy walking distance to the Plaza Mayor and Sol (although if you're lugging suitcases, you may want to opt to take a taxi/Uber for arrival/departure). The bedroom with the twin beds is on the small side, but the living room/ dining room area is very spacious. We took advantage of the washer and dryer, which both worked great. The apt is only up 1.5 flights of stairs, so we never used the elevator. Wifi worked well. I don't think we used the heating/cooling system or the kitchen appliances so I can't speak to those but everything appeared to be in good working order. It is located on a busy street so if you insist on sleeping with the windows open, this place may not for you - the soundproof windows reduced the vehicle noise to a low rumble, so I slept well with the windows closed and the addition of a little white noise - and I don't recall hearing any noise from the upstairs neighbors. I would stay here again!
