My husband and I stayed here for 10 nights in October.
Pros: The view from the balcony is wonderful! We loved people watching from our balcony every morning and night. It was fun to see the daily ebb and flow of activity in Plaza Mayor. (If you are a light sleeper or plan to go to bed before midnight, make sure you have a white noise app.)
The location was also great! We loved being within walking distance of the entire city center. We found that we rarely used the metro since we were so close to everything.
Regarding the actual apartment, the bed was really comfortable, despite it being a pull-out. We're not super tall (5'3" and 5'8"), so we sort of slept diagonally so that one of us wasn't trapped against the back of the sofa. In the bathroom the water pressure was good and the shower was really nice. The furnishing and décor was nice in an IKEA sort of way. There was a lot of good storage space and really good Wi-Fi, too. The TV was nice, and we enjoyed that Netflix was provided.
Cons: Despite "English" being listed as a language that the host speaks, this was not the case. That was a bit of a frustration since it left us to figure out how to use the washing machine and kitchen appliances on our own.
Also, there were no paper products or toiletries in the apartment. (Some of this is noted in the listing, but just be aware.) There was no toilet paper except for the roll on the holder. There were also no napkins, paper towels, or facial tissues. There was also no laundry soap, shampoo, or coffee, even though there was a coffee maker. There was hand soap in the bathroom, and dish soap under the kitchen sink. Oddly, there were bath towels, but no wash cloths. Because of this, we ended up hitting a near-by grocery store on our first night and spending about 20 euros on those necessities. We missed those extra thoughtful touches that were typical of AirBnBs 6 or 7 years ago.
Another inconvenience is that there wasn't a good place to hang clothes or towels to dry. There was one small ladder-like drying rack that needed to lean against a wall, so we ended up draping our washed clothes and bath towels over chair backs and open cupboard doors. A real drying rack or wash line would be great!
Overall we enjoyed our stay here, but we missed the old-school AirBnB experience of being able to connect with our host.
