Our overall experience was average. Not the most convenient place for a couple and if you plan to go in and out throughout the day.
Place is big and spacious but for two people you really don't need the extra space. The apartment is in the 5th floor and the building has no elevator so if you forget something on the way out be ready to climb up 5 floors to pick whatever it is you need. The building were the apartment is had a lot of garbage (as in bags full of garbage) at the entrance, so bad smells and just not a good feeling.
Also, not a good place for a light sleeper, there are air drafts and just house noises that would definitely disrupt your sleep.
My recommendation is that if you are travelling with just one extra person (your partner), for the cost of staying here I think it would be way better to spend the extra 15-20 euros and get a room at a hotel, the marginal benefit of those 15 euros will get you long ways. However if you are traveling with 4 to 6 people then this place would be awesome, as the cost obviously would be really low per person. Overall considering all you get for what you are paying for two people I would recommend a different place (hotel or whatnot).
