This is a great place to stay, really good location, a couple of minutes walk from Rossio metro station. The surrounding streets have cafe's and restaurants but just under the apartment is 2 or three really good and cheap places to have Menu del dia which will leave you very full for 11 euros. A 10 minute or so walk up to the castle. A couple of streets away from the high street shops.
The host was very good at communicating and let us take our bags before check in time. The place was spotless and had everything we needed for a couple of nights accommodation. We were a group of 3 friends and really enjoyed having a bedroom each!
The apartment is up a few flights of steep steps so if you aren't very mobile it wouldn't be ideal but other than that it is highly recommended.
