We have been in Fabios apartment shortly after New Years Eve and can report that it’s really great. It has everything you would possibly need (including high-speed internet), is extremely modern, cleverly structured and clean. The hidden second bathroom was a nice surprise even for two people only. :-)
The location is pretty close to all the sights in Sevilla which you can do by walking easily. We even found a free parking space on the bank of the river. Fabio was of great help and answered all questions.
So, to summarize, we are very happy that we selected this apartment. It totally fit our needs.
