This is a beautiful, comfortable little apartment, and the location is FANTASTIC! Nice, lively neighborhood but not touristy and quiet enough at night so you can rest. The street is loaded with tapas bars and cafes, and is easy walking to many lovely non-touristy parts of town with great restaurants and shops. Or even Sagrada Familia! The Metro is 5 minutes, and it's easy to catch a taxi. There is a grocery store and a produce market next door!
The apartment is bright, clean and sunny with nice amenities like a nespresso ;)
The air conditioner was a life saver as we had a heat wave when we stayed.
The kitchen is servicable, it's great for basics but not if pure a master chef (go eat tapas anyway!). The shower drain in main bath is slow as everyone says buy a small price to pay for such a picturesque old building! The third bedroom is quite small and opens onto the elevator shaft, which you can hear operating quite loudly so put a sound sleeper in there. It's fine!
I recommend this lovely spot with all my heart and will miss it!
