I don't want to sound overly negative, but I owe other potential visitors an accurate account of this property:
Pluses / It is a newly renovated space, well equipped (Very large smart tv, Nespresso, electric juicer, toaster...) with a Loft feel (High Ceiling, open space, but the bedroom has a sliding door). The location is top notch, with bus stop at the doorsteps, and almost all the old city center within a 20 min walk range. It comes with a nearby parking spot which is a rare feature downtown Sevilla. Fast Wi-fi. Communication is smooth and you'll find a kind welcome package on arrival (soft drinks, a bottle of wine)
Minuses / Some shortcomings in the renovation spoiled the experience a bit (In the bedroom you can hear an almost permanent sort of compressor sound, you also get disturbed-and at wee hours-by the upstairs neighbor dragging furniture...It is a GF accommodation and the main access door from the street hasn't been replaced leaving room for incredible amounts of dirt/dust/insects to get within the pre-entrance to the flat. Because of that, and although the glass door/windows are high quality, the place is not completely soundproof from street noise. Anyway, you'll depend on the Aircon permanently. It is rather dark most part of the day and gets over sunny after 7pm.
My conclusion is that it is a very convenient property but for short stays only.
