This is a fab apartment with a lift and AMAZING terrace and location for the price. The apartment is so clean and the hosts are right next door to sort any problems out.
We stayed as three adults. There is plenty of living space for three adults it was just the sleeping situation that you have to compromise on. Personally I think it is well worth doing for the location and cost of the apartment.
Just to let people know the front main bed has a very soft mattress so anyone with back or hip problems may have an issue with this. My sister is registered disabled and needs a shower seat. I emailed the hosts and they arranged for one to be available, excellent. We also had a really loud humming noise in the back bedroom on the first night and I messaged the host and this was sorted the following day, again excellent.
You will find basic provisions in the apartment to get you started which are most useful when you first arrive. I highly recommend a stay at this apartment.
