We loved our stay at Cesar's appartement. Communication was great and he always answered messages very quickly. Cesar was so kind to wait for us at the private underground parking when we arrived and showed us how everything worked in the apartment as well.
The apartment is big, nice and clean and there is aircon as well. It is well equipped and the bathroom even has all the toiletries needed and set up as if you are in a hotel.
The bed is comfortable if you enjoy a hard mattress.
The area itself is very residential which is very cool. When exiting the apartment turning left at the corner of Calle Leon XIII, you have a bakery with cheap coffee and fresh orange juice and bread and it's full of locals enjoying a drink and snack there. There is also a small convenience store across from the bakery if you want to stock up on snacks and food and drinks. If you turn turn when exiting the apartment you get to a scare with another bar and across from that you also have a nice kebab shop and ice cream parlour if you crave a late snack, which we had at 1.30am on a weekday. The bus into central is also right there and bus 1 takes you straight into Plaça de Espana which is convenient. It is also easy to walk around and takes around 20-25 min to walk towards the old town and cathedral area.
Wifi doesn't always work in the bedroom but works best by the dinner table and entrance.
We highly recommend Cesar's apartment and he's a great host.
