Pros:
My parents and I took a gamble on this airbnb as there were no previous reviews when we booked. There is a small elevator, which is helpful since we stayed on the 3rd floor. For the apartment itself, the value is very good for the size and cleanliness of the space. It looks newly renovated.
Convenient location near many, many restaurants and short walk to the Royal Palace.
My parents thought this was the best place we stayed at of the four we booked for our trip in different Spanish cities.
Cons:
Check-in was a bit difficult since I switched SIM cards when I got to Spain and also do not have Whatsapp, which they seem to use more than Airbnb messaging. Also, the key pickup location is different than the location of the apartment itself. Our check-in was delayed, but Alberto allowed us to leave our luggage with him while we went outside to explore for a bit and offered us refreshments.
On the weekend it does get loud outside, so that should be noted if anyone is planning to sleep on the sofa bed; the sound was not a problem for the bedroom.
Immediate back to back showers not recommended because there seems to be a limited supply of hot water. After showering, water tends to pool a bit right next to the shower, which we mopped up with a towel.
