Hi everyone, I was in JCyN's apartment for 3 nights with my girlfriend in mid December 2017.
The apartment is very nice, perfect for 2 persons, but can host up to 4 people.
We found it very clean and comfortable. Wireless, 2 TVs, fully equipped kitchen, AC both in bedroom and living room, 1 bathroom with shower/bath and hot water tank, a lot of infos about the city.
The place is inside a nice, clean and quite building in the town center, 2nd floor with elevator, windows on the inner patio. A few minutes by feet from all the main attractions. Railway station is about 10' by taxy and the airport about 20'. The building is in a pedestrian zone, but you can catch a taxy in the street (Cuesta del Rosario) about 100 meters away.
Hosts were extremely kind, professional, always available on phone and helped us with any need (from the apartment keys at late night on the arrival, to luggage custody on the last day). All communications were in fluent english (which is quite difficult to find in Spain... or Italy ;)
We had a very nice stay in Sevilla and my overall opinion on the apartment and its hosts is EXCELLENT.
