The hotel (hostel) may look ordinary from the outside, due to the metal bars on the doors - but gives a sense of security as there are multiple doors to get thru, before getting to your room (means carrying more keys though!). Also, for those that are not fit or have mobility issues, this is not the place for them. We had no major problems with the four flights of stairs - the description is 3rd floor but this is the European way, it actually is the 4th floor US.
The service staff were really good and courteous - even though they knew limited English (and our Spanish non-existent), we could communicate OK. We reached at 10 a.m and Carlos let us store our bags and freshen up in the 'staff' area, and gave us our room in a little over an hour, just enough for us to grab some breakfast and a quick stroll in the neighborhood. The room itself is a little tight,mostly due to the way the furniture is setup, but the microwave, refrigerator and hot water/shower all worked fine.
Carlos also helped us in confirming our return to the airport with the transport company, and was accommodating in taking care of our requests (towels, things to do nearby, etc.). All in all, we had a much better stay than expected, and the location is definitely a plus. There is a decent grocery/mini market close by, where we picked up essentials like water, juice, fruit and a coffee shop/bakery just across the street.
