Everything about this apartment is fantastic apart from one aspect.
The location could not be better - really convenient to every central attraction but also set on a quieter street with lots of excellent food options. The space is light and airy, with plenty of space to relax. Air conditioning was appreciated on a very warm weekend. Communication was also very good and clear throughout, and the affiliated airport transfer worked very well. There are some additional fees for additional things (e.g. E20 for late check-in, postage of lost items, etc.) but these are avoidable. There was also no option to leave luggage after 10am check-out on the day of departure, which would have been nice but is understandable.
The only drawback was the showers: there are two bathrooms and both have showers over bath tubs with no shower curtain or adjustable wall bracket - so showers have to be taken holding the shower head in one hand, and with water splashing onto the floor. The temperature and pressure were fine, but the lack of curtain or bracket so that you can stand beneath the water were disappointing for an apartment at this price point. If this is fixed in future the place will be perfect.
