My wife and I stayed at Puerta Catedral for 4 nights and were extremely surprised at how well everything was thought out. I will be quite honest, we are quite a picky couple - we've stayed at 5-star hotels as well as airbnb apartments - and we struggled to find anything wrong with Puerta Catedral.
1. The location is spectacular. You are less than a 2 minute walk from Seville's Catedral / Alcazar and all other historic sites.
2. The restaurants just downstairs are great. We would recommend Ovejas Negras as one of the best fusion-tapas that we found (recommended by the very friendly Puerta Catedral staff).
3. Customer service was outstanding. They have an office 5 minutes from the apartment building, where you can have a coffee, ask for advice, or go to their rooftop patio anytime during the day.
4. The pictures in the listing represent the exact state of the apartment, which has clearly been renovated not too long ago. Very modern and clean. Smart TV / Washer & Drier / AC etc. Everything that you need for a pleasant vacation.
Overall, if you are planning to visit Seville, this is the apartment & company you want to pick (they also own multiple other units in the same building and across the street, which I assume are just as good).
We will definitely be back to Seville, and without a doubt will use their service again!
