While I did enjoy my stay with A&A, I feel like I have to point out a couple of things that future guests should be aware of. First of all, for our part, the provided address was completely wrong. We booked the place with the understanding that it's located in the city center, but the real address was in fact Portobello. We had to buy traveler's cards (£20 x2) for our stay, which was an unnecessary expense if the host would have been truthful about the address from the very start. Unfortunately, we were informed of the real address when we were already at the airport and only when I specifically asked about it. We booked the place at least two weeks in advance, so there was plenty of time to inform us.
The apartment was fine except for the bathroom, which could benefit from some attention to hygienic standards. The ventilation is completely covered by dust and dirt, which could prove to be a problem for asthmatic guests. The shower stall was dirty too, like it hadn't been cleaned in years. The shower head has such a low water-pressure that you get wet but not clean -- if that makes any sense. The gravest mistake in the bathroom, however, was the lack of a bathroom mat. The stone floor is extremely slippery when wet and there is a real risk of hurting yourself. A small investment of £5 for a bathroom mattress would go a long way in avoiding accidents. Also, there was no cloth/towel rack, so you had no place for your clothes and towel while you took a shower. The towels were provided by the host but men might find them a little bit too small for their taste. So, if you like a bigger towel, bring your own.
So, to recap, Alejandro was a friendly, helpful, polite, and accommodating host, but as a guest you have to make sure the provided address is correct and you should take into consideration your own hygienic standards.
