The apartment is very central and convenient. There is a bakery just downstairs which is great for breakfast (avoid the "American diner" across the road). The apartment is also quite large. I imagine you could fit quite a few people in it, although we had one per bedroom. The price seemed pretty reasonable. If you want those things, this apartment is worth considering. If you book it, I recommend using the transfer from the airport, which is quick and reasonably priced - the driver will hand you the key to the place.
Some quick notes:
The apartment could do with a little attention in places, including the upstairs bathroom sink cabinet which is water damaged (presumably because there is no shower curtain). When we were there, the front door didn't seem to close very securely. The latch was damaged in such a way that it didn't stay shut tight. It still closed, and you had to use the key to get back in. It just didn't feel the most secure.
The apartment is advertised with air conditioning - it has air conditioning, by way of standalone air conditioners, but be aware that, in the bedrooms, you will have to rearrange the furniture a fair bit to use it by getting the pipes out of the window (and there's nothing to stop hot air getting in through the windows). Also, it won't be very quiet when you have the windows open to use the a/c (because it is so central). This didn't bother me but it bothered one of our group.
The host seems to have a tendency to make requests (/demands with 'please' attached) in ALLCAPS, including by way of private messages on this platform. There were also a lot of instructions (some also in ALLCAPS) in the manual for the place which were, frankly, needlessly aggressive. An example of one is: "PLEASE TAKE OUT THE TRASH EVERY DAY NOT ONLY ONCE AFTER YOUR FEW DAYS STAY!" (exclamation mark in original). Why are you shouting at me as soon as I've reached a place I'm paying you to stay in? There are other examples, including threats that neighbours will call the police if you make noise at the wrong time. I assume they've had bad experiences with guests before but to be honest I feel this could be handled better.
Anyway, if you are fine with the above relatively minor issues, and you want something large and very central and not too expensive, it will do its job and you'll like it. We had a good time.
