We had a fantastic time staying in Millan's apartment (which is better than the photos) which has got everything you need and is in a great location. It is fully equipped and a good size; the bed is comfortable as is the sofa, dining table, the washing machine was handy. The water supply and shower is good, the wifi (you can pay extra to have this if you want) signal is fantastic. The building is really quiet. There is a bar downstairs which you can hear people chatting if you have the windows open but it always shuts by 11ish and it is also a nice bar to have a coffee.
We planned to stay for 2 months but stayed a bit longer because Corralejo is great. Town beach is only a 2/3 minute walk from the apartment as is Rock Island bar and the old town and harbour. We bought bikes (only 100 euros from the sports shop in las palmeiras) too and liked cycling to flag beach (15 minutes) for windsurfing and just around the town. There is a great gym round the corner which you can pay daily (5 euros) or weekly (18 euros) which we joined for the months we are here - classes are brilliant and the machines and weights are decent.
Overall, a great time with everything in the apartment functional and comfortable and the location great. On top of this, Millan and Maria (his keyholder) are fantastic to deal with - efficient, helpful and polite. Thanks to them both.
Have a good holiday if you stay - you won't be disappointed!
